I listen to music on Spotify like 8 hours per day every day. I listen to all sorts of music too. I don’t want to own every song I listen to, but I want to be able to rapidly access a library of songs and playlists that I select and the service allows me to do that. To say you don’t understand why someone would pay is being a little obtuse. I share a family plan with five other people, cuts the cost significantly.
