Time was there was no such model for a musician -- maybe in further time we will forget there ever was such a model. There still is really no such model for a painter (well, you can buy a print I guess) or a sculptor (they can sell a piece once but not usually repeated copies -- with the possible exception of Warhol's soup cans). As someone else has pointed out, there's a partial model for some such scientists (who can get a patent). When you think about it, some musicians are "waged" -- if they play in certain types of orchestra they are paid per performance regardless of the crowd. Does that make them less "creative"? Writers again fall into both camps. Some writers don't get paid per "sale" (for example journalists) but are simply waged and some have a mix taking both types of job.
I don't think the existence or otherwise of such a model tells us anything about how such a person *should* be paid though. In the end I don't feel too strongly about whether someone is paid a fixed amount or by selling individual copies of their work. I do feel pretty strongly about people making cases that their particular type of work is special and deserves exemption when we consider what is right or fair for people to expect.
