Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods Music - Battle, dungeon, explore and whatnot

I wonder, how does music work in the game? and how much power do we have to alter it, personalize it?

I can clearly notice that, say, battle music makes use of playlists. but how? and how much are those customizable? are they situational to the place we fight?

dungeons: does each one have its own unique tune?
