Its not the "just like you imagined" song.

There is a song in the new "final trailor" for the movie 300. (its on yahoo movies). anyway, its the very first song that plays for like 5 seconds. It sounds very similar to another classical song? Anyone know what the name of this song is? or the song it sounds similar to?

Something very operatic........
