As more music triggers are added to the mod, I thought it would be a good idea to list all of them for those who would like to see what exactly is required in-game for you to hear a particular track dynamically (i.e. without forcing it in the music player)

I've tried my best to list these as concisely as possible, but I apologise if things are still a bit confusing!
