Oh yeah those three would be good! I knew there were movie soundtracks that would work that I just wasn't thinking of. I'll have to listen to some sample tracks and see what would work best.
As for some stuff from my own collection,
Nox Arcana's Shadows of the Raven is great. It's all music inspired by Poe stories. It's especially good for the more culturally advanced domains like Dementlieu, Richemulot, or Mordent.
Midnight Syndicate's 13th Hour is also very good and I've used a lot of tracks from it. Works well for haunted houses or creepy, desolate places.
I've used tracks from just about all of the Midnight Syndicate and Nox Arcana albums, though I've probably used the most from 13th Hour and Shadow of the Raven. Generally each album is composed around a particular theme, so for example, Grimm Tales has good stuff for dealing with shadow fey or boogymen. The only thing with them is that a lot of them have spoken parts here or there, so it's best to pick and choose tracks.
The Black Hole soundtrack has John Barry's excellent score and is now available on I-Tunes. The main theme is very haunting although it may be recognizable to those who grew up with that movie. Six Robots, Durant is Dead, and Start the Countdown are two other very good tracks from that soundtrack.
Resident Evil 10 Year Anniversary is a collection of music from the video game series and has some good low key ominous tracks as well as a number of good tension or battle tracks
The Castlevania: Symphony of the Night soundtrack is another one that I've used a lot of tracks from.
And thanks for the compliment on the scenery
