And really, there is something here for everybody. For people looking for straight up party bangers there are more than a few options, but for stuffier folks who like their music to be critically approved and maybe slightly more underground, bands like The xx, Four Tet, Amon Tobin, Animal Collective and LCD Soundsystem are all featured. A few classic hip hop cuts -- 2 Live Crew, Dead Prez, Salt N Pepa -- are repped here, but there is one song that really doesn't belong with any of the others. Can you guess which one?
"Project X" is in theaters now, and the soundtrack is in stores, but if you want to figure out what that awesome song you heard was check it out on the next page.
