Britney Spears is nothing short of an iconic popstar, getting her big break into the late-90s pop scene with her hugely popular debut album …Baby One More Time. The album resulted in her first No. 1 album, first No. 1 single and first two GRAMMY nominations, including for Best New Artist, all when she was just 17 years old. Since then she has released eight more studio albums with countless hits and received more GRAMMY nominations plus a win for Best Dance Recording at the 47th GRAMMY Awards for "Toxic." As Spears plots her "round two" Domination of Las Vegas with her new 2019 residency, we want to know which of her songs is your favorite?

Which Britney song gets you dancing and singing out loud no matter where you are? Is it her debut single "…Baby One More Time," her dance-pop anthem "Toxic," her collab with Madonna "Me Against The Music," the unabashedly sexy "I'm a Slave 4 U," or one of her other songs?
