Good to hear there are fans of Loreena McKennit, Dead Can Dance's
Aion, and the LoTR soundtracks. I'd consider all those, and
maybe a few selections from Enya or Burzum's ambient albums.
Also, I've looked up some of the Oblivion sound files on Youtube and I find those very enjoyable. If I were playing full-time on PC again, I might try to get those (or even buy the game just to snag them, if I could).
