ListenFrnd – Music match app with compatibility score
A social media app focused on sharing and discussing music. Make friends online by meeting other people with a similar music compatibility score. Quickly find people who like your taste in music – punk, indie, dance etc

Shazzam lets you connect to your facebook friends, but yeah, not quite nailed it as a network of likeminded music fans. Some other options exist though, here https://www.lifewire.com/best-social-music-sites-2438411
Good idea, Spotify just doesn’t do this, and youtube is a list of hate comments, nothing I have found lets you share music with others into the same genre. Any ideas anyone?
Try Playlist app, it lets you invite friends to listen to music together.
