People, not algorithms, are the beating heart of the streaming music industry. If you’re a regular reader of Enterprise, you know our fondness for playlists on Apple Music and Spotify. Turns out, they’re not created by algorithms, but by “small teams of anonymous, hardcore music fans race to solve the record industry’s toughest problem,” writes Reggie Ugwu for BuzzFeed in the epic “Inside the Playlist Factory.” “We’ve come to expect that virtually all of our problems can be solved with code, so much so that we summon it unthinkingly before doing almost anything: from choosing what movie to watch, to finding a doctor … But what if music is somehow different? What if there’s something immeasurable but essential in the space between what is now called “discovery” and, you know, that old stupidly human ritual of finding and falling in love with a song? Algorithms excel at the former, but the latter is stubborn heritage: It’s your father’s old record collection, your sister’s stash of mixtapes, a close friend’s desert island soundtrack of choice.” (This story is brought to you by the Apple Music playlist “Behind the Boards: Butch Vig.”)
