There are a gazillion sites selling Royalty free music. That's why I ask. I just want a few top ones and I can let my guy doing the videos decide which interface he likes better.
I expect to pay per song, much as I do for stock photos. I don't trust any sites that claim the music is completely free.
Ideally, I'd set up an account with some credits and he picks what he needs for the videos I assign him.
