Thank you for making gd levels with my songs!

Reminder: You're free to use my songs anywhere, in anything, without any restrictions.

But: ZUN is author of original songs, I just remixed them. So basically songs are belong to touhou. But considering touhou is almost copyright free, especially music, this shouldn't cause any problems.

Anyways, just in case - touhou copyright rules: https://en.touhouwiki.net/wiki/Touhou_Wiki:Copyrights
