Hi, I'm sorry to hear that you've had copyright issues, I composed the OST of the game myself, and I never intended for it to cause any copyright issues.
I have the OST uploaded to YouTube, maybe that was the problem... the copyrights were set to "Standard YouTube License" by default, I've changed it to Creative Commons. I hope that this will stop causing copyright issues.
I'm very sorry about what happened, it was totally unintentional.
