That's really neat, thanks for sharing! I'm gonna have to give that one a listen. I love that it's based on the book directly.
Howard Shore, the composer for the movie scores, got an Oscar for best original soundtrack for the first and third movies, and the third one got best original song for a song Annie Lennox sang for it. They're definitely worth having a listen to. :) You can find them all on YouTube. I can't choose a favorite song out of them, but this one brightens my day every time I hear. it. ^^
