The unique thing with this song is that you're going with your teammates as the song comes, and you crouch behind some sandsacks as you meet the enemy, and the song is at 0:57. That happened to me, and it was just so epic!!

Skaara's music sets the scene for something Epic, then Kenny's is the Background music for the Epic event.
