Singing and playing Matt’s song is using his idea freely. Deciding where Matt’s recording may exist is taking control over his labor.

But music cannot be shared as an idea. It can be demonstrated/performed. If my idea has costs associated in order to be able to share it, and I don't receive any value in return then I stop sharing my idea because I can't afford it. Does fewer musical ideas being shared also not hold humanity back? Should I be forced to labour without compensation in order to perform an idea that should flow freely? Rhetorical but feel to if you have answers. I certainly don't.
