Convened by high-concept ADD multitasker Damon Albarn, this Afro-futurist jam session adds roiling rhythms from 71-year-old drummer Tony Allen – known for the immortal grooves he cut with Fela Kuti in the Seventies – to corroded space-age keyboards (Albarn) and low-gravity bass lines (Flea). The group offers rides to a crew of collaborators. Erykah Badu gets cyborg-y (see "Hey, Shooter"); Ghanian rapper M.anifest and Malian singer Fatoumata Diawara represent; techno legend Mark Ernestus mixes. The results may be the most forward-looking music you hear all year.

Listen to Rocket Juice and the Moon's "Hey, Shooter" (Feat Eryka Badu):

“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."
