Could someone please list the albums, or songs that have that "dark organ", "church organ", feel to it? Like that whole Toccata and Fugue in D minor thing? Links would also be great. I just don't want to have to search through every album, as my collection is already so big.

These (Thread 40320) threads (Thread 46977) might be good starting places. A couple posts down, the second one becomes more about dark choral pieces.

^ Thanks man!

You're welcome. :)
