The most haunting music you ever heard?

The soundtrack to Magnolia hints at haunting....Its a great piece of mucic and deffinatly can give you some chills....

"Haunting" as in "gets inside your head and your nervous system and won't go away" -- probably, for me, an album titled "Alina," music composed by Arvo Part, on the ECM label. It is just this side of silence, and it is achingly beautiful.

Another vote for Sufjan Stevens' "John Wayne Gacy, Jr.". Quite possibly the most moved I have ever been, in any direction, by any song ever.
