Scary Music!! by Anthony Larson (November 12, 2006)
I really think that this is a great horror film soundtrack, much better than the film itself. A great blend of Omenesque choral themes and freaky 80's synth horror.
The chilling use of the childrens choir reminds me also of Lalo Schifrin's Amityville Horror theme.
There is also a very gothic adult choir used for some of the death scenes, this horrified me as a kid!
