That's the problem though, Sarge.
Guitar Hero can get a total of 8 unique songs on their series.
Rocksmith (a game with no proven track record) is able to have 2 Muse songs on it's disc.
Rock Band has a total of one song that was released four years ago.
What the hell is HMX doing wrong in trying to get more Muse songs for the platform? Their main rival had no issues doing it time and again, while the new kid on the block can do it the first time out. Yes, I know that Rocksmith doesn't need masters to have songs in the game, but the point still stands that they were able to license those songs.
