As a side note, the Kronos Quartet did an amazing job with the soundtrack for Requiem for a Dream which is a great movie and book. The soundtrack is hauntingly arranged with moments that elicit supreme sorrow, madness, and joy. The major theme of the soundtrack is a beautiful solo violin aria that seems to linger on top of a melodic cello/ piano base. The best example of this is perhaps track 32 of the soundtrack, though track 1 spices it up with a bit of a techno mix. This music is ideal for listening to either loudly or softly, and if you have seen the movie or read the book, it can even have an emotional affect. I feel that is the highest tribute to which a movie soundtrack can hope to attain. If when I am listening, I feel angry, happy, disoriented or heartbroken, I know that the music has fulfilled its purpose.
