Over on the ScoreHero forums, Pengwyns noticed that during a Rock Band commercial, one that's airing on MTV promoting the latest round of MTV2 Rock Band DLC, they accidentally reveal a few DLC songs that we've never heard about. During said commercial, they quickly scroll through a set list and on it there are four songs with a "NOT READY TO TEST" label including DLC tracks from Nirvana, Machine Head and Nine Inch Nails. Check the newly discovered DLC tracks below and cross those gaming fingers in hopes of seeing another NIN track pack.
  • "Aesthetics of Hate" by Machine Head
  • "Afterlife" by Avenged Sevenfold
  • "Breed" by Nirvana
  • "Burn" by Nine Inch Nails
