I'm also entertained by the booklet with its highly revisionist notes about the evolving "style" of the music on TNG, stating that the blandness of the music was a creative decision on McCarthy's part that was more in line with the producers wishes rather than Berman's costcutting and total lack of musical vision.
I don't see why you'd think that's what the booklet says. As I read it, it makes it very clear that the evolution of McCarthy's style was in response to Berman's wishes. Yes, it says McCarthy "chose to view" Berman's guidelines "as a creative challenge," but that certainly doesn't mean he wasn't obligated to follow Berman's instructions. It just means he tried to be as creative as he could within the limits he was required by his employer to observe.
