I think that the author has exhibited a total ignorance of the music business, past and present.
This statement alone is an example:
“Before, there was more of a 50/50 split, down the middle, between art and commerce, within the industry.”
When predicated on such an inane premise, anything else this person says is highly suspect.
Another case in point:
“Beforehand, stuff wasn’t forced-fed to the extent it now is. Music was ‘distributed’, not ‘mass-marketed’; there’s a difference…”
Has this person never heard of “Payola”? Probably not.
The music business is in better shape now than it has ever been. Writers are keeping control of their own publishing, technology has armed artists with recording tools that permit them to produce their own product, and musicians can actually make a decent living marketing their music independent of the “Deal”.
I would refer the author to one of my favorite quotes:
"The music business is a cruel and shallow money trench, a long plastic hallway where thieves and pimps run free, and good men die like dogs. There's also a negative side."
