I was speaking to a guy in the biz.... runs a studio full time doing commercials (video & audio) for radio and TV and other such things..... he told me just the other day that he used to be able to ask and get $10k for a certain sized project and now, he's lucky to get $2k to $5k for the same sized project.... then he added "if that much".
rates are down all over the place and that goes for musicians at the bottom of the market especially.
Publishers will make theirs ..... of that you can be sure, as will the big players like Pandora. They are adding ads and all sorts of income producing things. I've noticed the ads all over what used to be free Pandora radio on the internet.
