Great music, totally linked up with the film plot in meaningful ways and holds the tone or vibe throughout.
One major problem I had was the missing club tracks, these full-on techno, almost hardcore and metal sounding tracks that went with the dark, strobe light, club scenes were not included in the soundtrack and definitely should have been. To me these tracks/sounds were a huge part of the movie's soul, almost climatic in a sense as far as feeling the brunt of a connection with death and the intensity of realizing a loved one has died, and going through that experience of contact with the dead/underworld, and at the same time feeling that intensity dissipate and move on, healing the psyche.
