Good thing they changed the rule after Tommy to ban "concept albums" from being considered for Original scores. Technically, they didn't. Which is why Jekyll and Hyde and The Scarlet Pimpernel had eligible scores despite having originated with concept recordings. If the concept recording is material conceived for a stage production, then it is eligible. The issue in question is proving American Idiot was originally intended for the stage. I certainly don't know and I can't say I really care.
I didn't feel it was worthy of the award for the simple reason that I thought it was lousy. You obviously doesn't like the score for Piazza. Fine. But to say it is "lousy" is sort of doing you more harm than good. Was it too complex for your taste?
Are there any scores that are universally disliked? I think the point was "
more universally disliked" and the answer is "yes". There probably can never be a score that is universally disliked simply because someone had to write it. And someone decided to produce it. So that's two people right there who like it enough to do something with it.
