My remark about the corporate character of this music was not in reference to who wrote the songs. I'm sure the "artist" in question was born to a natural human mother, also, and not raised from a test tube in a record company's laboratory.
What is chiefly corporate about this music is not merely its endorsement and promotion by corporate entities but its production (including autotune, shameful for someone with any vocal talent), its aesthetic, its consumerism, its product placement, etc. Beneath the veneer of rebelliousness is a deep conformism, both in style and in content.
I won't dispute the question of talent. I think talent, in itself, is vastly overrated in our culture. Oftentimes the most loathsome garbage is defended on the grounds of "but they're so talented!" Talent is nothing without inspiration, without beauty, without the artistic sensitivity that cannot be achieved by acquiring a set of technical skills. If all we want is "talent," I can think of many bands of many genres who have undoubtedly great proficiency with their instruments, and who make complex and difficult music, which is nevertheless profoundly uninspired and dull.
