"Artists and music journalists have been coining genres for decades, based on sounds shared between artists. This new era for genre is derived from listener data and labelled by engineers who, Seaver says, never expected to become authorities on the matter. This speaks to the contradiction at the heart of Computing Taste: it’s both easier and harder to pinpoint a person’s music taste than you might expect. It all depends on what you think taste is. Spotify can tell us how many times we loop a favorite song, make reasonable assumptions about the genres that speak to us, and deduce from GPS data what we might want to hear in the gym as opposed to the office. But Seaver stresses that a key anthropological question remains unwrapped: why do people love the songs that they do?"
