For as long as there's been "Guitar Hero," actual guitar heroes have been trying to playing "Guitar Hero" and sucking at it. Just as being able to kick ass at the game doesn't mean you can play a real guitar, being able to shred a Flying V doesn't mean you can play the game. There's no better proof of that than the following videos of real live rock stars (and Miley Cyrus) playing "Guitar Hero" and making it clear that they should stick to the real thing. Of course, if they want to get better they can buy "Guitar Hero: Warriors of Rock," which comes out today. But we'd suggest they just stick to the real thing.
