The music to "Wicked" is glorious in spots..no doubt. In my mind, "Wicked" was more of a conventional musical however. "Avenue Q" was original, fresh, and smart. Was the music as pretty as "Wicked?" As majestic? As thrilling? No. But it was something very new. The characters, the story, and the clever lyrics are what carry "Q" and I do think that the Tony voters made the right choice.
I will say though, that Schwartz is understandably upset in that he has written very good scores such as "Godspell," "Pippin," and "The Magic Show" and they all, including "Wicked" have been overlooked. Perhaps he was looking for a bit of a lifetime acheivement award for "Wicked." I might not have argued that.

I know I'm condradicting myself here. I belived that "AQ" had a more original score than "Wicked," but I do feel that Schwartz has made many a valuable contribution to the theatre.
