A superb game like Mansions of Madness, especially the 2nd edition, deserves a great soundtrack to enhance atmosphere and gaming experience. The app provides a good "start" of tracks, but sadly the music gets repetitive rather quickly.
I put together a playlist for cthuloid games providing 18hours of creepy ambient music, smooth jazz and dance music from the 20s and 30s. If you're interested head over to spotify and check it out HERE
Thanks and have fun playing Mansions of Madness 2nd Edition!
There's an Arkham Horror playlist on Spotify, by Benton Barnett, that I always put on when playing anything Lovecraftian. It's a nice mix of 20's and 30's ragtime with big, ominous atmosphere. I'd post a link but I'm at work and they block Spotify's site.
EDIT: Here's a site that has a direct link to Spotify: LINK
EDIT #2: Forgot to say thanks to the OP for posting this link – I'll be checking out this playlist, as well!
Damn it Andy beat me to it. Played that music in a hotel at midnight once. People were freaking out, like refusing to go in hallways and freaked out at mirrors. The music gets to people for some reason. I couldn't believe it.
