I'm no musical expert, I don't know what an arpeggio is, so I'll stick with the emotions this song plays out to me in my review.
I've never played Wolfeinstein, never been much of a fan for FPS in general. I was expecting a fierce, bloody track of music, but was pleasantly surprised by the emotion and melody. The speech parts added to the feeling immensely. This song makes me a little sad, it makes me reflect on human history. It get me reflecting on the human tragedies in the past, and how they seem so senseless. Very memorable. I understand that there will always be someone offended by songs that remind them of things they want to forget, but I feel this is in no way a pro-Nazi track.
Bottom line, this is a very well done work of art. If you're looking for a sad, melancholic song of history, download it now.
