Even if they were entirely a corporate creation, who cares? I only really care about the final product and not the method by which it came about. They were good, and deserved all the success they received.
My real problems with the effects of "corporatized rock" which began in the 70s and lasted into the 90s, were the cases where studio execs pushed bands to load albums with fluff and filler, and save more of the "good stuff" to be sprinkled across the next several albums.
As much as I love the "album rock" era, this type of corporate greed was partially responsible for the end of it, and the resulting shift toward digital downloads of singles, and ultimately singles streaming.
Above commentary probably more appropriate for the other "what about music is on your mind" thread but, well, here we are.
