Not saying I hate the music but it does get a little dull and I would love to add my own music into the game. If there is way to change the music and hopefully choose your own music in a mod. That would be amazing Keep up the great work modders
the music files of this game are contained in three .fsb files. If you extract this and monkey around with them, you could theoretically replace any song with something of your choosing. This would not be possible at runtime though, you'd have to change the base files themselves. Simply put, just do what KillerKiwiJuice said, it'll be easier.
