Music is emotional, and so our listening often signals something deeply personal and private. Today, this means music streaming platforms are in a unique position within the greater platform economy: they have troves of data related to our emotional states, moods, and feelings. It’s a matter of unprecedented access to our interior lives, which is buffered by the flimsy illusion of privacy. When a user chooses, for example, a “private listening” session on Spotify, the effect is to make them feel that it’s a one-way relation between person and machine. Of course, that personalization process is Spotify’s way of selling users on its product. But, as it turns out, in a move that should not surprise anyone at this point, Spotify has been selling access to that listening data to multinational corporations.
