Is it possible to have a friend stream where users can share music within the app to a stream? Posts could be liked, commented, and reshared. This could allow users to share their favorite songs, playlist, and artists to their followers. There is already so much music sharing that is leaking outside Spotify to other platforms like Instagram stories, Facebook, and text messeges. Why not keep the users within the app and allow them to share and interact with each other on Spotify in a Friend Stream. The stream could also bring friend activity (see what friends are listening to in real time) to mobile.
