I'll just go with top 5 as he has so many good ones:

1. E.T. - The score DEFINES the movie IMO like no other.
2. Indiana Jones & The Last Crusade - Raiders may be definitive, but Last Crusade is simply moving...I give it a listen CONSTANTLY!
3. Empire Strikes Back - No need to explain.
4. Schindler's List - Gorgeous & equally as moving.
5. Jurassic Park - Definitive

special mention to this Dracula '80 score...I have it in my iPod, as well as Close Encounters. His integration of "when you wish upon a star" almost brings me to tears/
