This is my personal top 15 movie soundtracks. A difficult choice out of many great scores has been made. I didn't put Lord of the Rings, Star Wars, Titanic, Gladiator or Braveheart in it, because almost everyone uses them in their top scores. They're still great scores though. Feel free to comment, which one is your favourite?
