Can't you just dump them to a flash drive and they'll work when you're logged in?
Is there a legal way to transfer downloaded/purchased songs from Rockband 2 on PS3 into another PS3?
I don't think there is such an option, but it would be awesome if it worked.
You mean to someone else's PS3? Or will you use your PSN account on that other PS3 too?
That's the thing I hate about digital distribution and where we're going. When that becomes the norm, I'm out of this hobby. Too dumb.
