"There's nothing wrong with hitting the notes spot on, clear diction, wide vocal range, and some of the other things one may get from classical training."

Yep, and you don't hear whiny, nasally, breathy sounds either, with no breath control, and the inability to be heard with out a mic. Projection they have in spades, and they have learned to open their vocal tracts and sing from the diaphragm.

A breathy weak voice can be very alluring live in a small room, but I think the recording industry is using such a sound merely to sell 'sex'... amping the hell outof it does no real justice to it, anymore than taking a powerful voice and trying to 'wind it back' - like driving a Ferrari to the corner store...
