While playing the 2D beta today (as Unclean Beast, if relevant) I heard a new combat music I quite liked. I heard it only briefly though, and it never came came up again in that game or the next three. Are there pieces of background music in the game that show up only rarely among the "standard" ones? It would be nice to have some variety.
As a side note, if possible, a "jukebox" for selecting the tunes you like best to play would be great. Default being the current "background/combat/etc. depending on the situation" system, naturally. Some of the old Command and Conquer games had that (and others, I'm sure) and it was a nice feature.
