I would tend to agree, though the game and Guitar Hero have exposed people to some great, classic music that they would not have known otherwise. I’d rather have kids and people listen to some of the tunes on Guitar Hero/Rock Band than some of these “rap artists” and whatnot.
Also, on a related note, anyone who has Rock Band and the drum set should check out this. You can use the Rock Band drum controller (the newer one that comes with World Tour) with this piece of software and actually play the instrument. Very cool.
I don’t know if it’s dumbing down music so much as introducing potentional musicians. I’d sooner accuse electronica and digitized music of that than a game that gets people that wouldn’t touch a guitar to “pretend”.
