Well, I haven't heard any Ulver beyond Bergtatt and Nattens Madrigal, but Nagellstev was a piece I really enjoyed.

If you can compose a tune or a few riffs for my voice to follow, I could do that pretty well, I think. I wouldn't be able to write any words in Norsk, though; my knowledge of the language is basically limited to phonetics.

I've just finished listening to three pieces you recently added (march of death, norse tension and the menu) and I think they all fit pretty well. It also makes me think that the first one you presented (battle01) could be played when the missiles begin to fly. Is there a trigger for that in RTW?
