When these New Yorkers debuted in 2004, their flamboyant glam pop made them stars in Europe — not to mention a welcome new queer voice in rock. Three albums in, the Sisters are as gleefully hedonistic as ever: The beats still have that mirror-ball gleam, the slinky tunes still lodge themselves in your cranium, and Jake Shears' lyrics are still laced with not-quite-subtle sex talk ("Sting me like a bee/I want you to funk me"). Every song sounds like some other band, from the Bee Gees disco of the title track to the Talking Heads-y paranoia of "Running Out." But that's no reason to hate on this good-natured party.

“I'm Yours”

Jason Mraz re-emerged after his disappointing second album with this lead single, a Jack Johnson-esque ditty about giving yourself fully to someone else. The success of the reggae-tinged song (it earned two Grammy nods and a spot on the Billboard singles chart for well over a year) was something the folk-pop singer never predicted when he wrote it in 15 minutes at home. "I played a happy-hippie chord progression that would probably work without 50 different Bob Marley songs," he told Rolling Stone. "I thought, 'It's too novelty. This is a nursery rhyme,'" concluding that "you can never guess what's gonna be a hit."
