This music below is the theme of the movie The Usual Suspects. This film is very memorable to me, because I didn't know anything about it when I went to watch it and I was washed away by the ending. It was so well thought out and executed that I was rooted to my seat while watching the cast list rolling away.
During the end credits the music linked below was heard and so it's sort of attached to the experience I had in the cinema.
It's a very a nice piece of music, the haunting theme is sinister and dark. I like it very much. Give it a go by listening to this 3 minutes with your eyes closed as some kind of short relaxation concentrating only on the music. It's not your average movie theme:
