Spotify users want to be able to see who has taken the time to listen, enjoy and follow the music that they like. Spotify currently has it so you can see the number of followers a playlist has, but not who those people are. We should be able to see who has interests like us, and even take the time to go listen to some of their playlists as well. It altogether promotes unity and there are no downsides at all. No harm can possibly be done from knowing who likes the same music as you.
