Not sure if this is the correct place to put this specific request as I don't know if the music is part of AC or perhaps from a trailer music library. Anyway, I'm looking for the awesome track that is heard in the AC 4 gameplay trailer: Assassin's Creed 4 Black Flag - World Gameplay Premiere [UK] - YouTube (http://www.youtube.com/watch?v=9gNCqSebPBY&list=PL66280EDA3E565C72&index=39)

Any ideas?
