The greatest song yet by these twentysomething San Diego surf punks treats Nirvana like a killer thrift-shop find, with the guitars set to "mudslide" and an oh-well Nathan Williams drawling (possibly accidental) Kurt Cobain allusions like "We're probably just dumb." Gloomy though the lyrics may be ("no hope and no future" gets repeated), Williams sounds like a talented slacker with a sugar high, barreling into bigger and bigger choruses. Grimier bubblegrunge is seldom found under a school desk.

“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."
