For their first release since leaving the major label game and hanging their own shingle (what took so long?), Wilco deliver a seven-inch single that sounds like it was knocked out by a garage band, albeit a knowing one. "It's alright/You won't set the kids on fire/Oh I might," sings Jeff Tweedy, like he's having a late night talk to the mirror after some teenagers yelled "Dad rocker!" at him outside the mini-mart. Mikael Jorgensen adds some nasty-sounding Farfisa organ, guitarist Nels Cline spits riffs like he's having a seizure. Then everyone gets pretty on the chorus, because, well, they can. The B-side is a cheeky cover of Nick Lowe's "I Love My Label," in case you missed the subtext. Freedom is good.

“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."
