Pitchfork

Instant karma's gonna getcha; provided, that is, you plop down some dough on Instant Karma, a 21-track CD of John Lennon covers performed by some of your favorite artists (and, uh, Jack Johnson) with proceeds headed straight to Amnesty International's campaign to save Darfur.

Pitchfork faves the Flaming Lips, R.E.M., Big & Rich, the Postal Service, and Regina Spektor have donated tracks to the disc, while the likes of Willie Nelson, Duran Duran, and Ozzy Osbourne will offer up tracks for digital download. Also, Avril does "Imagine"; for some, a punchline, for others, manna from heaven.

Instant Karma: The Amnesty International Campaign to Save Darfur arrives June 12 via Warner Bros. And yes, some of these covers have been in the ether for a while, but hey, good cause!
