I know John Williams before Harry Potter and I was getting excited. Do not just be "magnum opus" Star Wars but also many other compositions to famous movies have done to me there. When I learned that veteran Williams also set to music Harry Potter, for me there was no stopping. As Harry Potter fan, I had to buy (the film is not as convincing as the soundtrack, the book is better) this soundtrack. With great variety and interesting medieval sounds succeeds John Williams to capture the mood of Harry Potter absolutely perfect. I can only recommend this soundtrack. (Unfortunately I'm a bit disappointed that Williams does not accompany the 4th movie. Hopefully he'll come back in the next films from Harry Potter)
