Casual mention in the liner notes, name on the guest list with back stage passes on the rare occasion that I can make your show, non-binding input into the bands first single, and negotiating role in which TV shows the bands songs appear in (which may require me to visit the set to make sure the song is being used appropriately in the scene).
Come to think of it, even if you don't go with Quickie, you may just wnat to agree to most of that anyway.
