Superman: The Movie - Soundtrack
I might go as far as to say that this is probably John Williams' second-best soundtrack--next to "Star Wars."
I've been watching this film with my two sons recently, and they seem as affected by the music as I was when I was a kid. The main title is probably the best superhero theme ever written. (And when you add those flying credits in the movie, it's even more incredible.) Now I can see why Brian Singer wanted to keep John Williams' theme for "Superman Returns" -- as it's permanently connected to the character of Superman.
