My biggest gripe with Rock Band is that its gonna cost an arm, leg and your first born. It comes loaded with 40-60 songs right? Then all the downloadable albums and such. They can't be cheap especially since they have to split the money between the dev, MS/Sony, the artist, label, etc. I would be very surprised if they were iTunes pricing of like $10 an album but even if they are, I have dozens and dozens of albums I would like to play but I sure as hell won't dish out more money to buy them for one game that will be replaced by Big Band or Jazz Band in a few years (unless they let you transfer Rock Band songs over the Rock Band 2 or whatever)
