Hello All, I recently got Rock Band 3 and I was wondering if it was possible to import previous songs from other discs? Apparently Rockband 2 and Green Day are the only offically supported methods. Are there others? I am not pirating but rather planning on purchasing the disc on ebay or such then would like to use them on RB 3. Also I saw something awhile back on using custom music with Rock Band? From what I remember it was only RB2, was there ever a update?
