Kanye clearly has no business singing, and at first his monotone makes you wonder why he tried. But his vocodered flatlining complements the opening heartbeats, and when his pitch hitches up on "you lose" and "system overload," his loneliness clicks — it feels like techno-pop blues. He tells his girl he's leaving, and eventually his voice does just that. The percussion doubles into a step routine, some noise screeches through, and the heartbeat returns alone.

“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."
