The Official Site for the Harry Potter and the Deathly Hallows Soundtrack has been launched and may be seen here!  The site has 30 second previews of all the songs (that we heard previously on Amazon), the interview with Alexandre Desplat as well as what versions of the soundtrack you can purchase!  It even has a listing of the bonus songs you get with the Collectors Edition:

1. Voldemort
2. Grimmauld Place
3. The Dumbledores
4. The Tale of the Three Brothers
5. Bellatrix
6. My Love Is Always Here

Order the regular soundtrack or limited edition.
