I have been making this app with my friends. It’s called MySound and you can share music from Spotify and Apple Music. You can open your friend’s playlists in Spotify or apple music (the app converts the playlist). You can also follow people and like their playlist. Pretty cool if you wanna check it out. Also follow me on there my username is @ Dylan iOS only:
