I'm surprised by the amount of support for this idea. Personally, I hate the dedicated band games. It's like buying a cd with 20 songs you don't like just to get the 2 songs you do like. I can't think of a single band who I'd want more than a dozen songs from, and I certainly wouldn't spend $60 for to get those dozen songs (a dozen is optimistic) and then another $10 to transfer the entire tracklist to my RB2 collection (cluttering it up with a myriad of unwanted songs).
I wouldn't complain about the dedicated band games if it weren't for the fact that once a song has been released in a dedicated game, it won't be released as dlc, and I hate the idea of closing the door on so many songs. There's some Green Day songs I want (haven't counted, but probably a dozen ) but not enough to spend $70 on, and now there's no chance they'll ever be available any other way.
Is there something wrong with the dlc solution? Don't most people just buy the games so they can import them into RB 1 or 2? I faithfully check out the new songs available every week: I love getting new songs for Rock Band, but I also like to limit it to songs that I actually enjoy. There's songs by most of the bands mentioned in the poll that I've been hoping would come out *cough* Hotel California *cough*, but if they're only gonna' be available in dedicated games I'll have to pass.
