Don't even lie! You're just as excited as any club kid that boundary-pushing pop sensation Lady Gaga is coming to Rock Band next week. So, get that tight-fitting pleather out of the closet and jam to the tracks you feel obligated to tell everyone you hate. Of course, you could pretend you "accidentally" bought the Gaga track pack, when you actually meant to purchase South Park's chubby charmer Eric Cartman's rendition of "Poker Face." Yup, it'll also be available. See, now you can cover up that undeniable desire to go goo-goo for Gaga under a veil of irony. Check out the full track list after the break.
