I was wondering how to add my own songs to the game, and at specific times/locations. Any help would be appreciated!
No easy way to do this. Only using some kind of modding API as far as I know. Currently there is only a tutroial how to replace songs.
That's unfortunate to hear. I hope someone can release a method soon, the songs are very limited in this game. I know there's a mod that adds more music, but it's not exactly my taste.
