Moar Ween, please. The Live in Chicago album would be sweet. And also some Arctic Monkeys.
Even though I won't be able to enjoy any new RBN stuff, it'd be pretty cool to see some of these in the game.
Has anyone ever tried reaching out to EarlyRise? They've got some good stuff, like Face Me. It sounds perfect for Rock Band and last I checked they don't have any major label.
Considering we got the Bedroom Intruder Song, I think that this couldn't be too impossible. Even if it just a remixed restaurant review, the man's got one hell of a voice. We also have been having a serious lack of short, funny novelty songs ever since Parry Gripp mysteriously disappeared.
Finally, I'm sure this has been asked a crapload of times, but has any authoring group ever branched out to the guys who make the Sonic music? I know there are some indie game tracks from games like Meatboy and VVVVVV, but how about a major game company? I have no idea how that would work out, but Crush 40's (and others') songs would be amazing to get into RB. Come on, you can't tell me that Live and Learn doesn't sound like it should be in this game.
I'll take it Genesis, ELO, Pink Floyd, Metallica, and Journey are out of the question...?
Has anyone tried for any of the lesser known artist from the Walking Dead soundtrack?
