This is going to change the game in a drastic way I think. We will start to hear more and more "underground" music flowing out to the public. Making it so bands who are serious don't need to fellate Radio stations for play, but shell out around $100 bucks to get their tracks up on Rock Band for the low prices of $0.99. Not a bad shake for them.
But it also does mean that we are going to see some of the more money hungry artist will be pumping out crap just to make a buck or two. Artists that may not even be worthy of being on the game in the first place, but they don't want to feel left out. But hey, maybe well get some Rammstein on here finally or maybe a few songs from Repo!. Who knows?
Here's where to get them if you are interested.
