I considered the show to be more about complicated plans, trickery, and intrigue between characters who were always trying to outwit each other, or tip the balance of events in their favour. This sort of heavy metal does not mesh at all with my idea of what it was about.
Of course all of that is pretty much irrelevant to me, because with that screaming I would hate it no matter how thematically appropriate it was. The song gets more bearable in the middle, but the beginning and end are just horrible. From 0:07 to 0:20 is literally just "BLAAaAAaaAaaAaAAaaAAaaAAAAAaAAaaAAaaAAaAAaAAARGH, *breathe* BLAAAAAaAAaaAaAAAAaAAaaaAAaaAAAA..."
If you like that sort of thing, fair enough, but for everyone who doesn't it's just painful.
