Wouldn't it be a great idea to have your own, or some type of music box in game. The music could be either craft-able pottery discs, or some pop-up menu that pulls from a youtube. (The idea came from a mod on MC where you can post pictures from imgur on your server, and even connect to wurm's IRC inside a MC server (computer-craft...), so if the rather is possible, I know pulling music is too). It would be awesome to throw some sick medieval parties complete with some music. QL could even be based on how long a clip you can play from 1 sec at 1QL to 100 sec at 100 QL or something like that.
