Pretty Nifty
Just a few suggestions other than the obvious "OMG SOUND" which would have made the Guitar part pure sex, I might add. For one, your menu button should have a filled in rectangle around the text that says menu, so we don't have to aim the mouse for such a thin line. Also, some better instructions for the guitar hero game would have been nice, it was kinda hard to see what letter I had to press to get the note to set fire :P
Overall quite swell, though, I must say.
