As far as I am aware, there are only 2 legitimate songs in Plazma Burst 2, and that's the main menu and when you encounter enemies. I was thinking there could be some additional music to use in the Advanced level editor, maybe to set the mood of the map. For example, fighting a losing battle against an army of Usurpation Soldiers would have some dire, dramatic music playing. This music could be turned on and off through triggers.
It's just a thought and I feel it would certainly be interesting.
