I'll probably get flamed for this, but I actually wouldn't have minded a radically different approach to the sound of Enterprise. Guitars and synth in there, with the orchestral strings pushed even further into the background.
There's a difference between a new approach, and turning your show into a vehicle for commercialism. For example. VOY's "Tsunkatse" was nothing more than an hour long infomercial for the WWE.
This ridiculousness reminds me of the Macross 7 anime, which was just a paper-thin excuse to produce J-Pop.
As far as the OP, this only reinforces my already low opinion of the UPN execs (especially Dawn Ostroff), and that they clearly had no clue about this show at all. It also reinforces my opinion that Berman and Brage get far too much shit from fans for stuff that was out of their control.
