But Spotify’s worth is more ephemeral. Its value—what makes it addictive for listeners, a necessity for artists, and a worthwhile investment for venture capitalists—lies in its algorithmic music discovery “products” and its ability to make the entire music industry conform to the new standards it sets. This means one thing: playlists are king, and particularly the ones curated by Spotify itself. An unprecedented amount of data (“skip rates” and “completion rates” determine whether a song survives) and “human-machine technology” are deployed to quantify your tastes. This is what lies behind the “magic” of Spotify.
