Okay, so I've had a request to post what rights people have to use my songs, so here you go:
-You may remix my music. Don't ask, you have my permission. (unless the description explicitly says not to remix it)
-My songs are free to use in any animation, game, or video, as long as you credit properly.
-You may use any of my songs in Geometry Dash.
-If you want me to make an OST for a game of yours, please message me and we'll talk about it.
