If you have listened to any of Hans Zimmer's work, this sounds quite like it.
Listen to Barbarian Horde from Gladiator (about the middle of the track on to the end), and then listen to He's a Pirate. Almost identical themes used.
I'm not complaining, as there usually isn't too much of a good thing.
All in all, a decent soundtrack, something you feel like a pirate with and it makes you want to go out and swashbuckle something...
