Ok so I know my Video Game Music thread wasn't highly successful so now it's time to try something similar...but for movie soundtracks.
A few of my personal favorites (aside from main themes like the Indiana Jones, Star Wars, or Harry Potter themes which will probably be mentioned quite a bit in this thread) are:
Aggressive Expansion - Dark Knight
Duel of the Fates - Phantom Menace
Battle of Yavin - A New Hope
Main Theme - Pokemon the First Movie
(sorry guys I couldn't resist that last one)
