So for the past few months I've been playing TB:RB on my roommate's PS3 and, well, what can I say, it's been nothing short of astounding. We bought Abbey Road and Pepper as DLC on their release days, so they're on his PS3. I finally decided to buy my own PS3 today (the copy of Beatles Rock Band is something I bought though) for when I move out of the apartment and we've been trying to transfer the DLC. We thought that if we had him log in on my new PS3 and use his account on Beatles Rock Band it would transfer the songs onto my hard drive, but for some reason my system won't even let him log on. Is there some way to transfer DLC or will I have to re-purchase the albums?
