Hello! Thanks for your comment and thans for doing a playthrough!
But I'm not quite sure how it's possible that the musics are under copywrite... They all come from EvokeMusic, and they are all guaranteed royaltee free...
Edit: I figured it out, you need an account on their website to use their music for free. But I also realized that their licence for games is much different so I will be taking them out until I find a replacement.
