'Best' piece of music from a film?

This one sprung to my mine instantly.

It is the end of the film but shouldn't spoil it for those who haven't seen it.

Cars, Women and music

I am not sure how it translates over twenty years, but when I saw the original 'assault on precinct 13'
what i remembered most was the soundtrack by Tangerine Dream. Fantastic music!

A couple from the Royal Tenenbaums:

Sting - Shape of my Heart at the end of Leon.

Joe versus the Volcano - the whole film has a superb soundtrack.

The bit in "Cry Freedom" when they sing Nkosi Sikelile Africa at Biko's funeral. I can't find a youtube link for it, but it's a powerful moment as the singers voice shouts "Amandla" then it goes into the song.

[M3CHA-MONK3Y]

Watchmen. Take a bow by Muse.

Doesn't matter what you think of the film, never have music and film blended so perfectly.

Anything by Lisa Gerrard - In particular the songs from Black Hawk Down (excellent), Galdiator and Man on Fire
