Ever since I started to play Assassin’s Creed IV: Black Flag and made it to Nassau (an island in the game) there is a background song or ambient song playing. It is one of the best things I have ever heard in any game. In fact when ever it would start to play I would stop what ever I was doing just to listen. All so found this song is used when you visit Kingston was well. Wanted to find out what it was called. Didn’t have any luck. How ever did find it on YouTube. Which that video is > here or below, they are calling it Kingston & Ambient Music #2. Give it a listen. It is even better with headphones on.
