I really like good soundtracks and have a decent collection. Here is my shot at a top 10 (in order):

1) The Lord of the Rings Trilogy
2) Star Wars (the first one, later entitled "A New Hope")
3) Gettysburg
4) Raiders of the Lost Ark
5) The Empire Strikes Back
6) Star Trek: The Wrath of Khan
7) Glory
8) Patton
9) Jaws
10) Rocky

I'd have to say that the first two (LotR & Star Wars) are perhaps as near perfect soundtracks that you can get. As soundtracks they excel, but also as simply music, there is hardly a track I'd even consider skipping. Many soundtracks have a great theme or two and the rest of the "music" seems to be almost random notes to match the movie, but not the first two soundtracks on my list.
I've a sneaking suspicion I'm missing a few soundtracks, but there you have my list as it stands right now.
