This household is full of Rock Band fans!! We own 1, 2, Legos, the Beatles, and Rock Band 3. Three by far is the best play for singers and added instruments. Here is our biggest issue: We love certain songs off of all the discs but it kills the fun when you have to put in RB1 for a few songs and switch back to 3 or whatever. Is there any chance of you guys releasing the contents of previous RB discs as DLC? Thanks.
