This is by the band Wardruna:
Wardruna: Runaljod - Yggdrasil YouTube mix
Lots of inspirational moods, rythms, etc. The lyrics are in some Nordic tongue, so cant' say anything about that. I'd guess that there's translation somewhere on the web. This particular video is over an hour.
Opening credits and theme song for HBO's "Vikings" TV series:
"If I Had a Heart" by Fever Ray
great mood, powerful imagery and the video is good too. Some of the lyrics are too modern, but the spirit of greed and lust is in there.
