Music was so important to this druggie classic that two soundtracks were released for the film. The first is your typical, songs featured in the movie type of OST. The other dropped a year later with songs that inspired the filmmakers. Both are stacked with the kind of cool guy post-punk that a lot of kids are drawing from in the indie scene today. If names like Brian Eno, New Order, and Joy Division aren't mainstays in your iTunes library, this soundtrack isn't a bad place to start.
