what is the name of that really popular song...
 

its that song thats in a lot of movies and commercials and stuff, it has a woman singing really high and has a big crescendo of instruments
its played alot in parts of movies where big battles are about to happen or people are going to do something heroic

its not the Enya song Only Time.

im sure many people have heard of it but i have no clue what the name is.

anybody know?

It could be - "fortuna, imperatrix mundi" from the Carmina Burana by Carl Orff.

I'm no opera buff though, it's what they play at some football matches as the teams come out.

This may want to be merged with the Master "What Song is This...?" list thread that's a sticky.

Not sure of the song, but Fortuna is a good guess.
