What do Galantis, Miike Snow, Sky Ferreira and Britney Spears' "Toxic" all have in common?

Christian Karlsson, the Swedish DJ and songwriter who spent the last 30-odd years becoming one of the most influential and untamed voices in modern music. 

Since his early days as a skateboarder-turned-rapper and punk rocker-turned-beatmaker, Karlsson has quietly stacked up top-tier credits and international awards, launching project after successful project. Yet, he's never explicitly made himself the center of attention. 

You may have heard of him as Bloodshy, one-half of the storied pop production duo Bloodshy & Avant, under which moniker he's worked with major artists from Christina Milian to Kylie Minogue, Madonna, Jennifer Lopez and more. Or perhaps you recognize him from the eclectic dance act Galantis. But you've never quite heard his full professional story — until now.

On Galantis' latest string of singles — the newest of which, “Dreamteam” featuring Neon Trees, will arrive on Oct. 27 — Karlsson opens up about his personal struggles with ADHD and gets back in touch with his rebellious music roots. After jumping from project to project, he's ready to connect the dots of his musical past into one sonic story. 

Below, Karlsson details the biggest milestones of his remarkable journey so far, from starting in punk rock to the latest chapter of Galantis.

Finding His Voice

It was punk rock and skateboarding that got me into music; the subculture of being political and against everything.

That expression is the most important part for me, and it will always be. I have a professional side, of course, but the seed that started it all was being in the punk rock and skateboard scene, and that will never go away. Every time I need inspiration, I take inspiration from subculture, hip-hop or anything inspiring to me. I think I'm too old today to understand what's going on with new subcultures, but I really hope that it's growing and that it's always there for young people. I think that's very important.

I started writing songs with a really bad acoustic guitar, learning three chords to write punk rock. My biggest wish in life was to get an electric, and once I did, I started a punk rock band when I was 14. 

I loved melodies from the start. I did like a lot of other punk rock too, but I was drawn to really cool, melodic punk rock. That's where it started. It's a good genre to start with, because it's easy.

Beat-Making A Name For Himself

[I became interested in making beats] when hip-hop came into skateboarding through House of Pain and Cypress Hill. I collected vinyl. I had Public Enemy and EPMD. I was already a fan of hip-hop, but when punk rock and hip-hop met, that was really interesting to me. 

All of a sudden, I really want a drum machine. That was my first step into production, learning an MPC 60 and starting to program. I was one of the first signed rappers in Sweden when I was 15. I did two albums and opened up for the Fugees in all of Europe. Jay-Z asked me to do a remix for "Hard Knock Life." 

In that way, I started as an artist. Producing for others was never anything that I planned. It wasn't that I wanted to be on stage. I just wanted to create music, and I didn't realize there were other people behind artists producing the songs. It's not like the punk rock bands I was listening to had a producer. That [understanding] came from hip-hop.

When I was 22, Quincy Jones invited me over to the U.S. the first time. I hardly spoke English. I worked with him on a lot of projects, actually. That's when I introduced that I actually know melodies, that I'm not only a beatmaker. I had a lot of great ideas for melody, and the melodies started to become a very important tool for me, as well as making something really fresh and somewhat left-field.

Finding The Formula

Bloodshy was my rap name. I had a group called Gold Mine where I was a producer, rapper and founder. Pontus [Winnberg] was the keyboard player in the live band. That's when we got to know each other, and then we split paths. I moved to Stockholm, and he was in Gothenburg. 

Later on, when I made that remix for Jay-Z and a bunch of other things, I invited Pontus to come and try making music with me. I was like "I went away a little bit from the hip-hop stuff. I'm trying to make beats for other people." Christina Milian was one of the first ones that was big for me, and Pontus came when I was doing that. That's the first time we worked together on something. 

Milian wasn't really signed or anything. It was more of an artist development thing Def Jam was doing. Instantly, I wanted to work with her. I believed in her, and we did a lot of songs together. That was the first really big project I took on as a serious production role.

Breaking The Charts…

After Christina Milian, I was working with a lot of artists and just writing so many ideas every day. I now understand that I was never the perfect producer because I never hit the mark of anything an artist was aiming for. I always hit a completely different place. I just need to go where I want to go, and if someone wants to tag along, that's amazing, but I'm not really the producer to say, "Can you do something like this?" I'm like, "No, I'm gonna do something else."

I actually wrote "Toxic" for Kylie Minogue. I think the A&R was on vacation or something, because they never got back to me. Then, I was working with another artist, Samantha Mumba, in L.A. The A&R for Britney was working across the hall and really wanted to meet me. I played him "Toxic." I didn't even play the whole thing. He came back like, "I want you to work with Britney, and I really liked the song you played," and it turned around really quickly. 

I had a very tough choice to make, because Janet Jackson flew me over to London, and she wanted to work with me at the time, too. I had to choose. That was a very tough decision for me, because I was a huge fan of Janet. But I felt like, with Britney, I had someone that could follow where I wanted to go and do some crazy stuff. Maybe I'm completely wrong, but Janet was really strong. She knew what she wanted to do and was telling you. I was super into it, but I felt like, if I'm going to do my crazy s—, maybe Britney's project was better fit for me.

From then on, me and Pontus were with Britney all the time, from being with her on the tour bus to different studios in different cities. She trusted us, which was great. We felt like we had freedom, and we had a great relationship with whoever she was working with at the time. I really liked working on [Spears' 2007 album] Blackout. We wrote so many great songs, and we really took the freedom and just went with it.

…And Breaking The Mold

Miike Snow started as me and Pontus being really fed up with Top 40 music. Everyone was just asking us to make another "Toxic" or whatever it was, and we decided not to work on other artists anymore. We didn't answer any emails or calls or anything like, Let's just do our own thing. 

We met Andrew Wyatt in a studio in New York. We really clicked with him and instantly started working on music together. Our plan was to release it on MySpace, and that was it, just follow the freedom. "Hey, if the song is eight minutes, it's f—ing eight minutes!" 

I'm really proud of the decision, and Miike Snow just grew. Probably the first 100 shows were tiny venues, like 100 people, and we're the opening act, traveling in a van, carrying all the gear and building our stage stuff. People are like, "You're a big producer, why are you doing this?" I was like, "I f—ing love doing this!" 

Miike Snow organically grew and started getting a lot of love and support from other musicians and creators. That was what we wanted. It was actually exactly the right love because someone was giving us love for the crazy s— that we liked to make. Then we started to play bigger festivals and tour like crazy.

Me and Pontus had been looking at the dance scene for a long time. You can hear that in our productions. There's a lot of electronic music and dance music in it, and we had it in Miike Snow. Then we started to DJ the parties after Miike Snow shows. 

I started to love DJing, and we got really tight with Sebastian Ingrosso and Steve Angello — before they were Swedish House Mafia. They were huge fans of Miike Snow and the song "Sylvia," and we took a peek into their world. I was with them in Ibiza like, Oh my god, this is crazy. That sparked something in me that kept on going until, eventually, the Miike Snow DJ sets I was playing became so disconnected from Miike Snow that I had to start a new thing. Indie dance could only take me that far into the night, right? I needed to be a little bit more clubby. And I just needed a vehicle for that.

Nurturing New Talent

I [met Sky Ferreira] when she was 13. She DMed me on MySpace, and I was blown away. This was the cockiest 13-year-old girl I'd ever spoken to. She keeps on saying she's the best at everything. I showed Pontus like, "There's something about this girl. She's so confident, and everything she's saying, I'm buying." 

She was cool in the club space. Sky is gonna hate me saying this, but I was like Maybe she's a new Uffie. Uffie was, like, blowing up at the time, and I worked with Uffie later in my career because I was a huge fan. Anyway, I'm like "maybe she's like Uffie" because she was in the headspace of dance music and indie, that Ed Banger [Records] world that Uffie was in. Then Sky sent me [a clip of] her singing. I'm like, "You gotta be kidding."

I dove right in and started to create a sound working with her, inviting people that I thought would be good for the project.

Starting Galantis

I took a break from touring with Miike Snow after 600 shows or something. I felt like I was a little bit cornered, like how I felt when I started Miike Snow to get away from Top 40. I felt pinned down in this touring thing, and I needed quicker output. 

Linus [Eklöw] was a good friend of mine, who remixed "Animal" by Miike Snow and my first Sky Ferreira song, "One." We started to talk, and I said "I'm going to start my own thing. We should work together," and that's how Galantis started.

I knew I had something when DJs started coming out with pop songs. It wasn't just techno DJs like Richie Hawtin anymore. That's when I felt like, This is what I do. I write songs and DJ. These guys were great, but I've been doing this way longer, so if you want a songwriter that can DJ, I'm like, "Alright, let me show you how." I just wanted to throw all my s— out the door as quickly as possible, because I knew if the world was ready, then this would be amazing.

Galantis was so important to me. I struggle with ADHD, and that's why I call the first album Pharmacy because I needed to go back into the studio and make so much music. I just wanted to feel good again about creating, because I wasn't creating as much on tour. This is my medication, and then I also wanted something that was an "upper," something that was happy and leaned the way I wanted to feel. 

I said to myself and Linus, "I only want happy, cool-feeling dance music, but I don't want to be cheesy." There is a line. When you think about Motown, it's all cool, but it's also happy vibes. Why can't we try to get that into dance music? Cool, but happy, warm and inspiring without being cheesy. That's what I was going for, anyway.

I think "Peanut Butter Jelly" is the most like that. Now, people are gonna read this and be like, "Well, that's cheesy," and I'm gonna say, "No, it's not!"

Getting Personal

I'm chasing freedom all the time in my music. Miike Snow is so much freedom, but I'm writing the songs with Pontus and Andrew, so it's not the complete freedom I get in Galantis. Now, I can pick any vocal and work with anyone, and dance music was the way I wanted to express myself because I was so into DJing. 

I wrote [Galantis'] "Bang Bang" because I've never told anyone really about my ADHD, and I just wanted it out there. Recently, I've come into different communities, and hearing about ADHD from other people has helped me a lot. That's what I want to do with the song, give something back and tell my story.

"Koala" definitely hits very close to home in terms of just doing my own thing wherever it goes and not being scared of going there. This is something that doesn't sound like anything else I know. It's a weird one, but I love it. 

I wrote it with a very good friend of mine, Andrew Bullimore aka Beatbullyz's, who I wrote "No Money" with. His son is singing "No Money." He was 10 at the time. And I was back with Bully and writing, and he had an idea where his now two sons could sing a song to his newborn daughter. The mom is from Australia, and his sons call her Koala. So Bully's two sons are singing to their little sister about Koala.

He sent me a little snippet singing it with his boys. I had, like, five studio sessions going, and I threw everything away, just skipped everything and worked on this. That's how much I felt like, I just want to go where this is taking me. That's what inspires me every day, coming back to freedom. I just did it because I felt like I wanted to do that, and now I'm really happy that we're putting it out.

The third recent single is "Dream Team." That's a very collaborative record with some people that I'm working with more and more. The idea was sent to me, and I was drawn to that little bit of something punk rock. I heard so many different pieces of music in one song that I felt very inspired to work on it. 

If "Koala" was like, Zoom, here it is;  this is the other type — when you're drawn to it, you like it, and then you have to keep on working on it. At times, I wanted to give up so badly, but there's something in me that won't ever give up on that challenge; some type of pressure I put on myself. This is a collaborative record with other people, and we're sending it back and forth. Snippets were changing, but it was a cool journey, and sometimes that's what it takes to make a record. I'm not scared to put it down and take it back up again. I'll never give up. 

It's like "Peanut Butter Jelly." I wrote that thing 10 years before it came out. I pitched that to so many artists, and no one liked it. Everyone hated it, and every time someone disliked it, the more I used to be like, I'm gonna put it out one day, and I did — and it's a pretty big record for Galantis, actually.

It gets easier with experience, to have more output but less of a stressful life. You know how to do stuff. In the beginning, I was living in the studio basically, but today, I get more music out than ever, and I don't have to live in the studio anymore. I do create music 24/7 anyway. It's just in my head, you know?

How Skrillex & Fred Again.. Became Dance Music's Favorite Friendship: A Timeline

Britney Spears recently posted a message on Instagram that asserted she'd never return to the music business. She later deleted it, which could be taken as a sign that she hasn't made this big decision with such finality. But it was certainly an alarming statement to her diehard fans eagerly awaiting new music.

It's fair to hold out hope that Spears will want to be a public entertainer and recording artist again in some ways — after all, she did just release a memoir, The Woman in Me, in October, and the book reveals a healing woman. And, of course, she scored a worldwide hit in 2022 with Elton John in "Hold Me Closer." 

Even if she never releases another piece of music, Spears already has quite the legacy. Between five No. 1 singles on the Billboard Hot 100, six No. 1 albums on the Billboard 200, and a GRAMMY win, her mark on pop music is undeniable. Part of that impact is courtesy of "Toxic," the danceable smash that was released as a single in January 2004 (and won Spears her GRAMMY in 2005).

In honor of the 20th anniversary of "Toxic," GRAMMY.com surveyed the pop superstar's hits and deep cuts from 1998 to the present in order to break down some of the most essential tracks in Spears' catalog. Between beautiful ballads and brazen bops, let the reminiscing commence.

"...Baby, One More Time," ...Baby One More Time (1998)

Written and co-produced by powerhouse Swedish pop producer Max Martin — a frequent collaborator throughout Spears' career — the singer's debut single was rewarded with some of the highest honors of the music industry when she was just 17 years old.

"...Baby, One More Time" topped the Billboard Hot 100 chart and was nominated for Best Female Pop Vocal Performance at the 42nd GRAMMY Awards. It has since sold over 10 million copies, and to this day remains one of her defining hits. (And to think it almost wasn't hers: According to Yahoo! News Australia, the song was reportedly originally offered to the Backstreet Boys.)

The song's instantly meteoric success was undoubtedly catapulted by its memorable video, which sees Spears dance her way through private school halls in a (now iconic) skimpy uniform. Seeing it performed visually cemented her image as a young, belly-baring flirt with girl-next-door looks, approachable style and enviable dancing skills, an archetype that little girls everywhere wanted to emulate.

"Oops!... I Did It Again," Oops!... I Did It Again (2000)

Spears further played with her innocent image on "Oops!... I Did It Again," a sassy song that suggests suitors aren't exactly safe with their heart in her hands. It was nominated for Best Female Pop Vocal Performance at the 43rd GRAMMYs.

"I think I did it again," she sings at the top of the track. "I made you believe we're more than just friends." Spawning another classic video and another trademark look (this time, a red catsuit), "Oops" emphasized Spears' further pivot into naughtiness and had thousands learning her choreography in a pre-YouTube era. 

Another Max Martin and Rami Yacoub production, "Oops" stuck at No. 9 on the Billboard Hot 100, but the album of the same name debuted at No. 1 on the Billboard 200 and set first-week records for sales by a woman artist at the time with 1,319,913 copies sold.

"Lucky," Oops!... I Did It Again (2000)

"Lucky" is a peppy song with a sprinkle of sadness on top. Its titular character is a Hollywood girl who seems to have it all, but there's no one to share her success with, so she is lonely and cries at night. It was a poignant sentiment, given her fame at the time, and was re-examined by fans in recent years as she fought for freedom from her conservatorship overseen by her father, Jamie Spears.

While it didn't manage to break the top 20 of the Hot 100, "Lucky" has always been a fan favorite. The song did break through internationally, though, becoming a No. 1 hit in three European countries as well as on Europe's overall pop chart.

"Dear Diary," Oops!... I Did It Again (2000)

Spears has worked with a global roster of songwriters and producers over the years, but the Oops! ballad "Dear Diary" marked a special moment for the star: it was the first album cut that she co-wrote.

While Oops!... I Did It Again largely showed a maturing Spears, the innocence and sweetness of "Dear Diary" served as a reminder that she was still just a teenager in the beginning of her stardom. The track also seemingly gave her the confidence to co-write more of her songs, as she had a hand in writing almost half of 2001's Britney and almost all of 2003's In the Zone.

"I'm a Slave 4 U," Britney (2001)

Spears went rather gritty on the lead single to her third, self-titled album. While earlier singles may have had a sexy wink within their words, the lyrics of "I'm a Slave 4 U" took a deeper plunge into the erotic zone. "All you people look at me like I'm a little girl," she sings defensively. "Well, did you ever think it'd be okay for me to step into this world?"

Along with the racy lyrics, Spears' visual performances of the song — a music video depiction of a steamy basement club night and a VMA performance that included dancing with an Albino Burmese python around her neck — added more cultural moments to her repertoire. 

"Overprotected," Britney (2001)

Spears' massive fame made her an early paparazzi magnet and led her to be sheltered by her management, record label and family. These topics are addressed head-on over the soaring notes of "Overprotected."

"Say hello to the girl that I am/ You're gonna have to see through my perspective," she declares on the opening verse. "I need to make mistakes just to learn who I am/ And I don't wanna be so damn protected."

The anthem foreshadowed her future hit "Piece of Me" — and the struggle for independence she'd later fight for during her conservatorship — but ultimately showed that she isn't afraid to speak her mind and fight for what's hers.

"I'm Not a Girl, Not Yet a Woman," Britney (2001)

After two bold statements with Britney's first two singles ("I'm a Slave 4 U" and "Overprotected"), Spears pumped the brakes on the notion of her growing up too fast in the ballad "I'm Not a Girl, Not Yet a Woman." The song appeared on her third album, Britney, and in the soundtrack for the road trip dramedy Crossroads.

"There is no need to protect me," she sings powerfully on the track, which appears to mirror her experience in real life at that moment in time. "It's time that I/ Learn to face up to this on my own/ I've seen so much more than you know now/ So don't tell me to shut my eyes." 

"Toxic," In the Zone (2003)

"Toxic" is an uptempo whirlwind of sampled Bollywood strings and Swedish pop drama crafted by the popular dance pop producers Bloodshy & Avant. Another single that took on a life of its own visually, the video served up another set of iconic looks: the deadly assassin, the sparkly nude bodysuit and the perky flight attendant.

"Toxic" remains Spears' biggest hit as of press time, now certified six-times platinum by the RIAA and the only song with more than one billion streams on Spotify. It also won Spears her one GRAMMY, for Best Dance Recording at the 47th GRAMMY Awards.

And 20 years after its release as a single, "Toxic" has had remarkable staying power on the pop charts. As of 2023, the song appeared on the Hot 100 in three different incarnations: the original track and the mash-ups "Toxic Pony" by Altégo and "Toxic Las Vegas" by Jamieson Shaw. 

"Everytime," In the Zone (2003)

By this era of Spears' discography, fans were more than used to autotune and other processed treatments on her singing — but "Everytime" is Spears in a more vulnerable and unplugged state. Co-written by Spears, the slow, melancholic ballad hit even harder because it was released after her public breakup with Justin Timberlake.

Fans hadn't heard anything quite as sad from Spears in her career as the pining lyrics of the chorus on "Everytime": "And every time I try to fly I fall/ Without my wings/ I feel so small/ I guess I need you, baby." The song became a fan favorite for the rawness of her vocal delivery, and was also a personal favorite for Spears during her Las Vegas concert residency.

"Womanizer," Circus (2008)

Spears' father began his role as her conservator in February 2008. Seven months later, she released "Womanizer," the lead single to her sixth album, Circus — which proved that no one was going to hold her down.

"You say I'm crazy," she sneers on the chorus of the engine-roaring uptempo track, which pokes fun at recent troubles with her ex-husband Kevin Federline. "I got your crazy!" she adds, sarcastically.

While the song's message focused on telling off a, well, womanizer, its commercial success showed Spears' new conservatorship meant nothing for her staying power. "Womanizer" was her first No. 1 hit on the Billboard Hot 100 since "...Baby, One More Time" topped the chart in January 1999; it also earned Spears her seventh GRAMMY nomination, for Best Dance Recording at the 2010 GRAMMYs.

"If You Seek Amy," Circus (2008)

If the title to the sing-songy "If You Seek Amy" is said out loud, it sounds like a sexual proposition. And that's exactly what makes this Max Martin-produced track so enjoyable.

Despite everything she was experiencing in her personal life, it offered evidence that Spears still knew how to poke fun at her staying at the center of attention. It's a perfect time capsule to an era when she was most wanted by the paparazzi.

"Hold It Against Me," Femme Fatale (2011)

Spears' "Hold It Against Me" flips an old chauvinistic joke into girl power — another clever piece added to the singer's puzzle. After being objectified so much over the course of her career, this song was her bid to put an end to it.

"Hold It Against Me" continued Spears' late 2000s hot streak into the 2010s. It earned the singer her fourth No. 1 on the Hot 100, following the chart-topping success of "3," her cheeky ode to threesomes, in 2009. 

"Work B—," Britney Jean (2013)

Spears assumes a faux British accent for "Work B—," a bossy cut made for gyms or the club. "You want a hot body? You want a Bugatti? You want a Maserati?" she asks over an insistent beat. "You better work, b—… now get to work, b—!"

Shortly after the track was released in 2013, Spears told English talk show host Alan Carr that the song is a tribute to her gay male friends, with whom she uses the word b— playfully and affectionately as a term of endearment. It became both a gay club anthem and a top 20 hit on the Hot 100 chart, and the video revived interest in Spears' dancing chops.

"Slumber Party (feat. Tinashe), Glory (2016)

A slightly different sound for Spears compared to her pop and dance productions, "Slumber Party" features Tinashe with a lyrical cadence that is more in the R&B singer's realm. It's perhaps the Spears song with the most urban radio feel since "I'm a Slave 4 U."

Fans may also remember "Slumber Party" fondly for what was once a romantic reason: Spears' now ex-husband Sam Asghari was cast as the leading man in the lingerie-heavy music video; it's how they first met each other.

"Hold Me Closer" with Elton John, The Lockdown Sessions (2022)

What better way to celebrate a big feat than with a massive collaboration? Nine months after Spears' long-fought conservatorship was terminated, she dropped a team-up with none other than Sir Elton John.

The unexpected duo released "Hold Me Closer," a soaring duet that interpolates parts of John's beloved hits "Tiny Dancer," "Don't Go Breaking My Heart" and "The One" into a singular modern mix. And though Spears is more of a background vocalist, her first release in six years marked quite the comeback: "Hold Me Closer" topped the Billboard Adult Top 40 and the Hot Dance/Electronic Songs charts, and reached No. 6 on the Hot 100.

As of press time, "Hold Me Closer" is the last song that Spears has released to date. While it's possible that there may not be any more recordings to follow, it's also safe to say she has surprised the world more than once before.

How Many GRAMMYs Has Britney Spears Won? 10 Questions About The "Hold Me Closer" Singer Answered

A quick Google search of "top 2004 songs" can be summarized simply: What a time to be alive.

While it was arguably the year of Usher — who scored four Billboard Hot 100 chart-toppers in 2004, including the year's biggest song, the Lil Jon- and Ludacris-assisted "Yeah!" — there were countless hits that have aged impeccably. Even 20 years later, there isn't a dance floor or karaoke bar that wouldn't go wild for J-Kwon's "Tipsy" or Kelly Clarkson's "Since U Been Gone."

Whether you were jamming to them on your iPod Mini or ripping them off of Limewire, revisit 24 tracks that made an impact — and still serve up the vibes 20 years later.

Julia Michaels landed her first major songwriting gig at just 18 years old. 

Fresh out of school, she’d cold pitched a little company named Walt Disney with a song she thought would suit an upcoming series. That song went on to soundtrack a popular Disney Channel show called "Austin & Ally."

Michaels quickly developed a reputation for her quick work and therapeutic approach to songwriting, and, in her early 20s, was transforming pop music via her confessional and slightly quirky perspective. The L.A.-based artist was soon writing with pop’s A-listers — from Britney Spears to Justin Bieber and Ed Sheeran, producing songs that gave the world insight into the contours of the biggest star’s internal worlds. 

"I'm grateful that I've been able to work with artists that allow the space for vulnerability and for authenticity, and for us to be able to speak openly and honestly about things we're going through," Michaels tells GRAMMY.com.

With a knack for emotional precision and complexity, Michaels has been trusted to transmute icons' revelatory moments into song: post-divorce comeback anthems, breakup bangers, even apologies. You’d be hard-pressed to find a songwriter better able to spin pain into a punchline than Michaels.

It’s one of many reasons Disney tapped her to score Wish, a recently-released mega musical feature that’s been chosen by the Studio to celebrate their 100th anniversary. Her idiosyncratic and confessional style lends a fresh perspective to protagonist Asha, while the songs remain rose-colored, dreamy, heart-lurching and classically Disney.

At age 30, Michaels is the youngest ever songwriter to score an entire Disney feature. But that's not her only major accolade: Michaels has been nominated for three GRAMMY Awards, most recently for Marren Morris' "Circles Around This Town" — which was given the nod for Best Country Song at the 2023 GRAMMYs. At the 60th GRAMMY Awards, Michaels was nominated for Best New Artist.

The phenom spoke with GRAMMY.com about some of the hits that made her one of the industry's most in-demand writers — and led to her biggest gig yet.  

"Sorry" - Justin Bieber (2015)

I had met a producer named Josh Goodwin, and he had asked for us to write some songs and see what we could come up with.  We had written two songs, and one of them I don't think ever saw the light of day. The other was "Sorry." 

"Used To Love You" - Gwen Stefani (2016)

I was asked to do some sessions with Gwen and my friend Justin Tranter. It was my first session with her but not his, so they had already known each other.

I wasn't entirely sure what I was gonna walk into or what she would feel comfortable talking to me about. And she was just so open and so lovely and vulnerable. She had these journal entries; in the midst of all of these thoughts and feelings she’d written down she had said: “I don't know why I cried, but I think it's because I remembered for the first time since I hated you that I used to love you.” She kept on reading from her journal and I stopped her and said "No, no, no, that’s a song." So we wrote it and it was just beautiful, she was very happy with it.

Every session is different, every artist is different, everybody writes differently. So sometimes I'm not sure what role I need to take that day. Gwen was very much in control of her narrative and vision, and what she wanted to talk about, so I just followed her footsteps.

I'm not really one for small talk. I think that's why I am still here. I like to get down to the heart of somebody and I know that takes a lot of trust. I'm grateful that I've been able to work with artists that allow the space for vulnerability and for authenticity, and for us to be able to speak openly and honestly about things we're going through.

I don't really have any qualms with walking in a room and being like, "Okay, but how are you really doing?" Not the L.A. version of how are you doing. Like no, how are you actually doing?

"Slumber Party" feat. Tinashe - Britney Spears (2016)

I met her [Britney] after writing a song that she liked, and then we started writing together. 

That was pretty surreal. I don't really fangirl a lot; I've been in enough rooms with people to know that we all laugh the same and cry the same and bleed the same. But then I remember hearing Britney sing this into the microphone for the first time and I just began melting into the floor, in shock and awe. 

I’d done something like eight songs for the album, and writing with her was so special. She has pop melodies wholly ingrained in who she is, so everything that she's saying just sounds like the perfect pop song. She also had her own narratives and she knew what she wanted to write about. We would literally just pull the microphone up to her face so she could sing melodies and we would write songs according to all the melodies and just go from there.

I remember just writing all the time and trying to find a sound that she felt suited her best. A I knew she wanted to do things that still had some vulnerability, but she's Britney Spears — she wanted to have a really fun pop record also. So we tried to cater to that as much as we could.

"This Wish" (2023)

This was the first song I wrote for Wish and it was the first song to come out for the movie. I was called in 2020 by [Walt Disney Music President] Tom McDougall and he asked me if I would like to try to write a song for a new movie, but didn't tell me that it was for the 100th anniversary of Disney's animation movies. Off of this little sort of blurb that he had sent me, I wrote this song about hope and being courageous, and taking a chance and being brave. I thought that was just such a beautiful message.

If he had told me that it was the 100th anniversary, I probably would have been really stressed out. I'm a Disney fan. I've been a Disney fan since I was a kid; I love Disney songs. And so there was already that added pressure to make something that's going to stand the test of time. But I also think that because I grew up with [Disney] it is probably in my psyche more than I even know. And so I wanted to make a song that felt really classic and really powerful and really beautiful, but also still sounded like something that I would write.

How Ilsey Transformed From Hit Songwriter To Artist On 'From The Valley': "I Have The Freedom To Say What I Want"

If you’re a music fan looking to restock your library with some new reads, you’re in luck. With the second half of the year comes a dearth of new music books recounting the life and times of some of the most celebrated artists in the history of the artform are hitting shelves. 

From Britney Spears' much talked-about memoir that tackles the tabloid tumult of her life and Barbra Streisand’s highly anticipated autobiography (which clocks in at nearly 1,000 pages), to tomes that recount the lives of Tupac Shakur and Dolly Parton, it’s time to get reading. Read on for some of the best music-related new and upcoming books to add to your collection. 

The Woman In Me

By Britney Spears

One of the most highly anticipated books of the year, Spears' memoir has been a blockbuster in the weeks since its release. When it was announced that the singer was writing a book, fans and observers braced themselves for what she would reveal when it comes to her tumultuous life and career. The result is a no-holds-barred look at how an innocent girl from Louisiana became swept up in the tsunami of fame, as well as the resulting wake. 

The Woman in Me details Spears' halcyon younger years as part of the "New Mickey Mouse Club," her explosive career, the blossoming and collapse of her relationship with Justin Timberlake, and the punishing conservatorship concocted by her father. Spears doesn’t hold back, but also shouts out the figures who provided solace and kindness: Madonna, Elton John, Mariah Carey, and former Jive Records president Clive Calder. The Woman In Me proves to be an unflinching, eye-opening look at the swirling tornado of music, fame, love and family, for better or for worse. 

My Name is Barbra

By Barbra Streisand

Since her early '60s breakout to her current status as a bona fide living legend, Barbra Streisand has lived a lot of life. Streisand's 992-page tome breaks down her humble beginnings growing up in Williamsburg, Brooklyn and her subsequent stratospheric life during which she received a whopping 46 GRAMMY nominations and released many timeless songs. Along the way, she also became the first female in the history of moviemaking to write, produce, direct and star in a major motion picture (Yentl). 

It’s all a long time coming, considering Jackie Onassis first approached Streisand to chronicle her triumphant life in 1984 (at the time, the former first lady was editor of Doubleday and Streisand was a mere 20 years into her iconic career). "Frankly, I thought at 42 I was too young, with much more work still to come," Striesand recently told Vanity Fair. It’s an understatement considering all that’s happened since.

THE LYRICS: 1956 to Present

By Paul McCartney

One of the most celebrated artists of all time, McCartney's genius songwriting is on full, glimmering display in THE LYRICS. Newly released in a one volume paperback edition, the book puts the Beatles' way with words front and center while offering popcorn-worthy backstory. 

Originally published to acclaim in 2021, the updated version includes additional material and insight from Macca himself on the creation of some of the most indelible hits in music history, including the 1965 Beatles hit "Daytripper." 

"The riff became one of our most well-known and you still often hear it played when you walk into guitar shops," wrote McCartney of the track. "It’s one of those songs that revolves around the riff. Some songs are hung onto a chord progression. Others, like this, are driven by the riff." 

Behind the Seams: My Life in Rhinestones

By Dolly Parton 

"It costs a lot of money to look this cheap!" So says luminary Dolly Parton, in a self-deprecating and witty and also patently untrue famous turn of phrase. While Parton’s life story has been recounted numerous times on the page and on screen, Behind the Seams zeros in on not just her trials and tribulations, but her unmistakable style. 

Packed with nearly 500 photographs, the book traces Parton’s looks from the sacks she used to dress in as a child in poverty to the flamboyant visuals associated with her stardom. "I’ve been at this so long, I’ve worn some of the most bizarre things," Parton recently told the Guardian. "My hairdos have always been so out there. At the time you think you look good, then you look back on it, like, what was I thinking?"

Thank You (Falettinme Be Mice Elf Agin)

By Sly Stone

The 80-year-old reclusive frontman of Sly and the Family Stone has certainly lived a lot of life. From his early days as part of the gospel vocal group the Stewart Four, Stone and his family band later became fixtures of the charts from the late '60s into the mid-'70s; a journey traced in the new book Thank You (Falettinme Be Mice Elf Agin), named after their 1969 song of the same name.  

Known for funky, soulful and earworm signature hits including "Dance to the Music" and "Everyday People," the band won over the hearts of America, influencing legions of fans (including Herbie Hanckock and Miles Davis) and gaining a few enemies (the Black Panther Party). The book chronicles those ups and downs (including drug abuse), tracking Stone up to the modern era, which includes receiving the Recording Academy's Lifetime Achievement Special Merit Award in 2017. 

Becoming Ella Fitzgerald: The Jazz Singer Who Transformed American Song

By Judith Tick

Ella Fitzgerald is one of America’s most iconic voices and the full breadth of her story will be told in the first major biography since her death in 1996. Known as the First Lady of Song, the 13-time GRAMMY winner is known for her swingin’ standards, sultry ballads, scat and everything in between.

Out Nov. 21, the vocalist’s historic career is recounted by musicologist Judith Tick, who reflects on her legend using new research, fresh interviews and rare recordings. The result is a portrait of an undeniable talent and the obstacles she was up against, from her early days at the Apollo Theater to her passionate zeal for recording and performing up until her later years. 

"Ella was two people," her longtime drummer Gregg Field told GRAMMY.com in 2020. "She was very humble, very shy and generous. But when she walked on stage she was hardcore and didn’t know how to sing unless it was coming from her heart."

World Within a Song: Music That Changed My Life and Life That Changed My Music

By Jeff Tweedy

Aside from his extensive discography with Wilco and beyond, Jeff Tweedy is the author of three books: his memoir  Let’s Go (So We Can Get Back), a meditation on creativity called How to Write One Song, and his latest, World Within a Song. The latter expertly examines a variety of songs by a disparate spate of artists, from Rosalía to Billie Eilish with Tweedy’s singular take on what makes each song stand out along with what he dubs "Rememories," short blurbs that recount moments from his own life and times. 

Much like his songwriting prowess, it’s a book where Tweedy’s way with words shine with shimmering eloquence. "My experience of my own emotions is that they all interact," Tweedy told GRAMMY.com last year. "They aren't individual, isolated things that you experience one at a time, and I think that's a really beautiful thing about being alive."

Tupac Shakur: The Authorized Biography

By Staci Robinson

One of the giants of hip-hop finally gets his due with an official recounting of his life and times. Here his legend is told by the authoritative Staci Robinson, an expert on the star who previously wrote Tupac Remembered: Bearing Witness to a Life and Legacy and served as executive producer of the FX documentary series "Dear Mama: The Saga of Afeni and Tupac Shakur."

Here, Robinson reflects on Tupac’s legacy from a modern perspective, and tracks the history of race in America alongside the rapper’s life and times, from the turbulent '60s to the Rodney King riots. Along the way are the stories behind the songs including "Brenda’s Got a Baby." 

"In between shots (of filming the movie Juice) I wrote it," Shakur is quoted saying in Robinson’s book. "I was crying too. That’s how I knew everybody else would cry, ’cause I was crying.’"
