One of the biggest problems I often face with my productions is music. I always end up searching for non-copyrighted existing music everywhere and sometimes I find what I need and sometimes it's sub-par to say the least. But that's unfortunately one of the things that's often difficult, or impossible, to spend money on in tiny productions. As with any other profession, I have never wanted any composer to work for free on anything - but what say the composers out there? Are you just happy to get your work featured in films that can't pay (obviously with contracts that pay you if the films make money) or is that inappropriate? A few times I have reached out to artists and been able to use a song of theirs without any fees, provided the films didn't make large profits of course.
