Hope it's some help... from the sound, it seems the music is by the minimalist composer, Philip Glass. It is possibly from the movie The Truman Show -- Glass composed several pieces in that. For the musically inclined, it's a chord progression repeating over and over, maybe something along the lines of C minor-Aflat Major-Eflat Major-G7, then repeating. Good luck.

: Is this the one with the nice classical piano piece? I'm trying to figure that one out myself. Email me if you got an answer please.
