Muse – Knights of Cydonia

Will I ever master this song on Guitar Hero's hardest level?! I'd be happy with 3 stars at this point. I may be getting blisters and a stiff back. Don't laugh. It's not easy!
Gotta respect those guitarists! I mean, how do those guys have the stamina to play entire concerts, sometimes even piss drunk or stoned? All I'm doing is tapping some fraking buttons on a toy!
