Well, its not a movie soundtrack, but its actually from a game... but i think it deserves respect because i think nobuo uemetsu (the composer) who wrote the pieces is a genius. He composed scores for the "final fantasy" series. and, yea he's really good....here's some of his work...
One of the best game themes I remember was for a game called "The Dig" - A LucasArts production and featured some very intense score work by Michael Land. I have the tracks at home and still listen to them!
John Williams, Danny Elfman, Alan Silvestri & James Horner are my favourite movie composers. Williams work is especially beautiful to my ears.
