Royalty for mixing or just a one off charge?

[Michael Brauer]

you don't really get to pick and choose. It takes a long time before artists are willing to give away their points. Sometimes, it's not worth spending the money to have a contract for getting a point on a radio or promo single. It'll never recoup. If it makes the album, then it's worth the effort because if the record sells a couple million, you'll get enough money, when all is said and done, to take a bus to work.
