I gathered tracks that creep in the background when playing: (diablo, silent hill, 1920's jazz etc).Whats everyone else listening to?

Playlist

The Thing ST would work fantastically for Antarctica. That's a great choice. And, of course, you can't go wrong with Silent Hill.

But mainly I just listen to the screams of my investigators.

Great selections!

We often listen to dark ambient from the Cryo Chamber label. Nothing too intense, very ominous. They have one compilation for Cthulhu and one for Azathoth!
Sadly, Azathoth was in the background as we watched the world burn last night.

I usually type up Arkham Horror OST on Youtube and find a playlist of different 1920's tracks with added creepy/space sounds. Fits the mood well enough.
