Much like the film, the soundtrack to Jackie Brown is criminally underrated. Possibly due to the fact that Pulp Fiction is almost perfect, possibly because people expect more surf music and uber quotable dialogue on the CD. This is QT's Blaxploitation film and that's reflected in the music in a big way. If you're into that kind of thing, it's a good collection of 70's funk, soul and a few oddities like Johnny Cash's "Tennesee Stud" and "Detroit 9000". The only real flaw is Pam Grier's "Long time woman" which sounds very much like an actress singing.
Give the dialogue a chance and it's very cool, laid back and you might even find yourself murmering "if you know Beumont..."and so on. The same goes for the music, it's a grower, trust me.
