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.
