Pick up 'The Sinking of the Titanic' by Gavin Bryars. Over 60 minutes of 'Autumn' played over and over again, the song rumored to have been the song played as the ship sank. The concept of the album is aimed at making it sound as if it was being played underwater.

Small clip:



My husband made a copy of it for me when we were in college. It never fails to make me cry.
