This update now adjusts the music's speed to fit the top speed of the character you're playing as, and also disables on netgames, since according to the wiki, it uses a function that isn't network safe. That makes it only intended to be played in single-player.
Also, I've heard about a Lua function that's been in the game that detects whether the music is a module file or not. I'll find out what it does soon, and then I'll release an all-new update.
