Guitar Hero has done more for real rock music in the past three years than any single band has in a long time.
Oh, yeah? So you're saying a fucking game that features rock songs is more important than the bands who wrote them to begin with?
No, scratch that, it sounds as though you're insinuating that a plastic controller shaped like a guitar is more important for "real rock music" than actually learning to play the real thing. Did you actually SEE the guitar hero south park episode? It speaks the truth.
Anyone who wants to play music, by all means, pick up guitar hero and play the shit out of it. But if you really want to play and you never take the time to learn a real instrument, you're pretty fucking retarded.
