If you were interested in the music played in the New Moon movie trailer that song is called 'Moving Mountains'. And for the Eclipse movie trailer the song is called '1000 ships of the underworld' they are both by Two Steps From Hell! They have other awesome songs on the album Invincible. I've heard that the first Twilight trailer had another song by them called 'Mercy in Darkness' but I couldn't find it anywhere:( Just thought you would like to know, you can get them on itunes. Peace, Love and Twilight!
