I have to say that the film would have been a lot less satisfying without this music and it really was the music in combination with the film that made me shed a tear.
Although be sure that you don't just skip to the last track, which is the most haunting and famous refrain !
But it also includes the songs from the films from the sad "He was a friend of mine" and "A love that will never grow old" to the upbeat "King of the Road" and "Devils right hand". A real mixture!
If you like the film (or even if you haven't seen it) this soundtrack is brilliant!
