Query: Harry Potter and the Sorcerer's Stone review:

I loved the cd! John Williams uses some themes frequently around all the songs, but I don't mind because the chosen themes are really good. My favorite is #19 (Hedwig's Theme). Though #11 (The Quidditch Match) was a bit of a disappointment it's still a really good song. I say you have to have read the four books to really appreciate the music. It's not enough to read the first one or see the movie. Trust me you'll enjoy a lot more this way.
