The other videos on the playlist were suggested by my wife. (I also used their song 'Animus' in my preview for that adventure on Facebook, as discussed in the linked post.) Doom 64 just has an awesome and super disturbing soundtrack by Aubrey Hodges, who made similar fantastic soundtracks for other video games, like the Playstation port of Doom.
Swans is a band I'm very fond of, and I think they fit the adventure perfectly. Sunn O))) was also recommended in several other places that I don't currently remember, and I used the TV Tropes page to pick out specific tracks. There are a ton of great suggestions there (and elsewhere) that I haven't used as well. Sunn O))), the Sicario soundtrack, Sakrateal, Nadja, and OM were suggested by various people on Google+. The Celtic Frost and Samael songs were recommended in the 2014 version of Death Frost Doom. (I can't guarantee that the link to the playlist will always work, so I'll list the songs/videos below as well.) So with some help from my wife, I put together a playlist on Youtube. I don't usually play background music during our group's games (the players usually take care of that), but running DFD is sort of a special occasion, and a lot of people have recommended using creepy ambient audio to enhance this most atmospheric adventure. So I'm running Death Frost Doom this Saturday.
