As I recently started building spawnable locations for my Viera mod, I couldn't help but wonder if it were possible to have the background music change upon entering certain locations? I have yet to come across a dungeon file that references any musical changes or arrangements, but I was hoping someone could shed some light on the topic. I've yet to check if music changes from biome to biome (I usually play with no BG music), or planet to planet, but if making a custom biome is required to have music change, then I'll go for it lol. Anyway, all help is greatly appreciated!
I don't think it's actually possible to have the music change when you enter a town. I do know for a fact though, that you can create an item that constantly plays music.
