So you all know the still alive song from portal? Well I was searching through songs that you can download for RB2 and I saw Still Alive, it was free too! Wanted to let you guys know about it cuz I thought it was pretty funny/cool.
Whether or not you are allowed you will need a converter. I believe that in-game music is in the .ogg format so MP3 players will just look at you like you are mad if you try to play it.
Dont have rb2, but this makes it more likely that I will get it. If you can import other in-game songs from hl2 and other games, then I might actually invest in it.
I got a bug up my but last week and decided to check out Frets on Fire again. I got a version of it and put a Rock Band 2 Mod on it so everything looks like Rock Band and grabbed song packs from every Guitar Hero game, both Rock Bands, a bunch of the DLC, and a giant list of user made songs that aren't in either game. Just pick up any USB Guitar Hero/Rock Band controller (I guess all the guitars work) and it works perfect. Same with the Drums. There are ins and outs to get other controllers to work too but I haven't bothered to check 'em out. I picked up a used Explorer from GH2 for $20.
