Comprising approximately 3.22% of DJ Hero's 93-song list of tracks, Cut Chemist and J.Period were announced today as joining the enormous list of artists contributing to the game. According to an emailed press release from Activision, J.Period will be creating two "exclusive" new mixes for the game, Q-Tip's "Good Thang" vs. Billy Squier's "Big Beat" (as seen above) and Gang Starr's "Just to Get a Rep" vs. Mobb Deep's "Shook Ones, Part 2."

Elusively, Activision says Cut Chemist will be offering "a mix featuring unreleased music from one of the biggest bands in the world." The publisher didn't offer word on whether or not that's a confirmation of the JoBro "Burnin' up" vs. Tupac's "All Eyez on Me" mash-up we've been hoping for, unfortunately.
