That's super weird because that song is a royalty-free song. I plan to make all the music myself for the full release (including the "copyrighted" one), but I just ran out of time for the demo. Frankly, I'm completely alone in this project.

I'll try disputing it and see what happens. Maybe it just claimed it because of some other music box audio that someone has in youtube's system. Which is stupid that they can even claim something like that since many music box songs will sound similar. This is what the claim said:
Music Box For Suspenseful Scenes - Vasya Sakal
Content owners: HAAWK for a 3rd Party
And hit the video so obnoxiously that I can't even use youtube's tools to edit the music.

To be fair, Youtube's Claim System is notoriously unfriendly to fair-use because pretty much anyone can claim anything for any reason and gain the benefits until someone does something about it which rarely happens because most people don't bother wanting to go through the hassle of fighting it.

Update on the copyright claim.. I disputed it yesterday and they already released the claim. So everyone should just dispute it if they get claimed for that music. It's probably some idiot who is auto-claiming a music box song, which shouldn't even be allowed since many music boxes will sound similar.
