Heh, all Julie Taymor did as far as music goes was write the lyrics to Endless Night.

I find it so amusing that they put her higher on the list than Hans, when Hans wrote so much already (Shadowland, Be Prepared, etc.)
My biggest complaint is the lack of trumpets. I really think they should've had one or two, especially for songs like "To Die For". If you listen to the movie version and then broadway's version, there's a remarkable difference. The French Horn taking over the trumpet parts just sounds too lyrical and flowing, and you really need a sharp brass sound at some of those moments. There also weren't any double reeds, but I didn't miss them too terribly.
However, I absolutely LOVE the percussion. If you think it's awesome on the CD, wait 'till you see the show. They adapt the boxes on either side of the stage for the percussionists, and you can watch them as they accompany the show. It was so much fun watching them go crazy in some of the songs.
All in all, I love the soundtrack. It's not perfect, but what is? The only 'problems' I have with it are inconsequential and minute.
