The game is great, but what I lack sometimes is a soundtrack for dungeons (especially when you have to solve riddles as soon as the area is clean of mobs). Why not putting your own stuff on?
What would be your music of a choice?
Personally, I am enjoying the game along with new subtle dark ambient/drone Black Swan - "Aeterna" (2012). The ominous ambience, sometimes medieval chorale in the background.
