Yodariquo said:Despite the numerous songs in the movie, I think this qualifies as the theme
The Lion King - This Land
YES.
Hans Zimmer made this score? Wow didnt know that, no wonder its so epic. Elton John with the songs, just perfect.
Dvader said:But themes do. Tell me you dont feel anything when you hear the Star Wars theme, the Indiana Jones theme, Jaws theme. These songs become instant links to the movie, just a few notes from them bring all the memories and emotions of that movie.
What you just said implies that they don't: you enjoy them because you associate them with the film itself. 
Stargate, almost missed that one, wow.
Rudy as well.
OMG Excaliber
Oh Dragonheart!!
Speed.
I know we are still missing some big ones.
OMG why does Dragon: The Bruce Lee Story have such an epic theme song. Seriously it plays in like every trailer.

Tell me to get back to rewriting this site so it's not horrible on mobile
The theme from The Excorcist - Tubular Bells
Yodariquo said:We should start nominating themes for denomination to narrow it down
Actually yeah. I have removed some from my list and have a rough 64 already. If you see any you don't think should be there go ahead. I think all yours are in.
Final call before we go to round one.
Two last ones from me. Both of these are written by the musical god Dave Stewart.
- Theme song from Lily Was Here (song of the same name).
- Theme of Cookie's Fortune - "I'm Coming Home."
Spirited Away theme is great.
