coachella line-up leaked

[froopy seal]

Gnarls Barkley and The Postal Service before Faithless? Arcade Fire and Feist before Jamiroquai? Modest Mouse before Underworld (and Kylie Minogue)?

Why do they already have a flyer/poster when no portions of line-up have been seen yet?

And who the frack are Mazzy Star, The Cars, Cut Copy, One Day as a Lion, Bon Iver, Roxy Music, Big Boi, Janelle Monae? Is this a US thing or am I just massively out of touch with contemporary music (not unlikely)?
