What is it about rock that drives reviewers to attempt to be clever?

Or is it a chicken and egg situation? I wonder if it started by reviewers Trying to match Dylan for wordsmithing etc...

You might run across the same style with some movie reviews/reviewers, but rock alone has virtually all reviewers at least taking a stab at it...

Well, at least we didn't have to read 'many think U2 is the best rock band right now, but no one expected them to go out and prove it'....
