And, based on this assumption, it seemed reasonable to hope that many "original versions" could be added to Rock Band, all Harmonix would have to do at this point is decide, "yeah, we should make a new version", ask the band again, and their stellar reputation would get it done.
But it sounds like this is not normally the real explanation. Good to know.
