I simply can't compose music. Like I can come up with simple scales and that stuff, but trying to compose something of a specific genre or to fit a certain situation is something I simply can't do. Part of that is because I always associate certain situations with songs/pieces I already know and I can never come up with anything else. Like, I always associate being underwater with the Dire Dire Docks/Jolly Roger Bay OST from Super Mario 64. It evens plays in my head when I'm underwater IRL. I can't think of anything else, even in my own games I have a copyrighted song playing in my head when visioning a certain situation.
I guess I'm stuck with using stock music or having to get someone else to compose music for my games.
