Favorite song from a movie?

I was just going through all of my favorited videos on YouTube and I got to wondering what some of your guys' favorite songs from movies are. Mine have got to be: ''Sweet Transvestite'' from Rocky Horror Picture Show  http://www.youtube.com/watch?v=wmxBb3RdnT8 Or ''Everybody wants to be a cat'' from Aristocats  http://www.youtube.com/watch?v=rkwKz7KlLBY What are yours? Elmo Favorite song from a movie?
barely any movies have good soundtracks... altough limp bizkit's - take a look around in MI was awesomeFavorite song from a movie?
I don't watch too many movies with songs in them but alot of skate videos have some really good music in them.
-The Good, The Bad, and the Ugly
-Star Wars
-Lord of the Rings
-28 Days Later
-Gladiator
-Last of the Mohicans
-A Clockwork Orange
-The Lion KingThose are just some examples of the many movies with wonderful soundtracks.
A few good soundtracks: The Wedding Singer, XXX, Top Gun, American PieBest Song? Heeeeereee we are! Born to be Kings! We're the Princes of the Universe!!!! Oh yeah. I said it. Highlander.
Philadelphia and City of Angels had AMAZING soundtracks, for the type of movies they are...Oh, and Forrest Gump. If I had to point out ONE song, I'd say Neil Young's Philadelphia fit the movie the best...  it was in the last scene, and easy to find on youtube
This is probably my favourite... or perhaps this... or maybe even this... 
This is Halloween or any track from Nightmare Before ChristmasThere are way too many movies to list.
Dreams by Van Halen, at the ending credits of Power Rangers: The Movie.
Hmmmm, probably any of the Monty Python movies, they cam up with some funny songs.
I forgot this Kenny Loggins classic...
