If you haven't already seen Billboard's master list of the 100 Greatest Choruses of the 21st Century, get ready to have some of the catchiest tunes of the 2000s stuck in your head all day. We've got Britney Spears, Kesha, Shaggy, Destiny's Child, Ludacris... the list goes on.
But while you blast our Greatest Choruses playlist (yes, we put one together for your listening pleasure), you may realize that even though you love belting out the hook of O-Town's "All or Nothing," you've forgotten how that one simple lyric goes -- that song is from 2001, after all. Sounds like a great opportunity to test your knowledge of some iconic lyrics, huh? We thought so too, so we also put together a little quiz.
