A-Trak and Diplo join DJ Hero 2, Jazzy Jeff and more come back for seconds

DJ Hero 2's already got more than a little turntablist cred with a roster that includes mixes from Tiesto, Deadmau5 and DJ Qbert -- earlier today, things went straight tazy with the addition of a few heavy hitters. Kanye West's touring DJ, A-Trak, and Major Lazer co-founder Diplo will also be contributing to the game's soundtrack, as will prolific DJ Hero 1 mixmasters DJ Jazzy Jeff, DJ Shadow, DJ Z-Trip and The Scratch Perverts. Man, those guys are disgusting.

You can check out a few of the mixes these august musicians are piecing together after the jump. We cannot wait to hear A-Trak mix up "O.P.P." and "ABC," in a mix we'll henceforth refer to as "The Freshest Song About Letters Ever"
