Episode One does have the best music, Duel of the Fates, Anakin's theme, Track 10, Track 11, and Qui Gon's funeral. I bought the soundtrack a week or two before the movie came out so I have had ample time to really get into it.
Episode Two seems to suck, but I should listen to it more.
The Empire Strikes back had most of its tracks be unbelievably terrible, but the asteroid chase and then the Falcon's escape from the Space Worm are pretty cool, and on the second cd (which I have lost) had a great track when Han Solo was being frozen in carbonite (listen to the music in the scene, then you'll know). But other than that it is terrible.
I don't have any others.
Congrats, tell me: are you a star wars guy?
