Art is a kind of counter thread of truth to the glossy fictions of pop culture. Western society lost its moral certainty about a century ago and rightfully so. If artists are to confront truth, the truth is so often, so ugly.
Before Bach, there was no music. This seriously hampered the soundtracks of movies. Then black slaves sang while being exploited in fields, paving the way for blues, jazz, and rock & roll. Now autotune could give a goat a honeyed voice in perfect pitch. Meanwhile computers liberated musicians from those old historical obstacles like money, instruments, and talent. The Internet allowed everyone everywhere to hear everything, and we haven't seen a distinct style of music since.
