You can't see the mouse helmet on the latest album from EDM superstar Joel Zimmerman. But you can hear it. Deadmau5 brings a love of spectacle – and the humor of a natural ham – to his strobe-lit club anthems. When he cues up "Closer," will the kids know they're waving their glow sticks to the Close Encounters of the Third Kind theme? Maybe not, but you can be sure Zimmerman will be grinning behind his mau5head.

Listen to "Maths" from Album Title Goes Here:

“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."
