The cd you refer to sounds like the one I'm looking at right now. I believe it came on a blister card, so there is no cover. The cd label is purple with black drawings of a haunted house and skulls. It plays just one track that runs about 45 minutes. It starts out with some sinister music and peals of thunder. There are some spooky laughs and screams later on. It is a very good background cd for Halloween.

I looked online, but I can't find it. If I see it, I'll post back.
