We're almost out with a game that features classical music available free for commercial use (cc and public domain) on
https://musopen.org/Most classical music, if played properly, sounds the same. That's probably why we recently got a youtube copyright claim by some German firm that takes care of some classical musicians' performance copyrights. We sent the musopen links and the claim was lifted. No problem.
Unfortunately, it started happening to the wonderful youtube lets-players that got our pre-release key. We've sent them the links, but that's a lot of hassle for everyone.
Is there an easy way to pre-report music? I don't even know how to put a game on that "youtube games" thing. Does anyone have any experience with this insanity? Please help
