Sorry bout this but Thunderhorse was in GH2, one of harmonix's other games, and the game would just get too boring if the same songs were on the new games, you know?

Definently everything but dragonforce, RB needs to find it's own speed metal band to make famous, and eventhough dethklok is in gh, metalocalypse is just too awesome not to include
