SoundtrackNet has posted a First Listen preview of the Pirates of the Caribbean: At World’s End soundtrack. The preview includes a nice long description of the Hans Zimmer score, including 30 second sound clips of each track.

Where the first film brought us the often-played “He’s a Pirate” theme, this third film brings in a whole new melody - a song called “Hoist the Colours”. Originally written for Pirates of the Caribbean: Dead Man’s Chest, this new pirate shanty is heard throughout the score, uniting all the pirates together under one melody. We’re also taken to Singapore, where Captain Sao Feng (Chow Yun Fat) gets his own Asian theme, as well as to the ends of the earth where not only do Will Turner (Orlando Bloom) and Elizabeth Swann (Keira Knightly) get a new love theme, but it’s a super-theme that also encompasses the lost love of Davy Jones and Calypso and is versatile enough to work as a new Jack Sparrow theme as well.
