I believe the seed of some deep meaningful friendships planted through music. we share playlists/tracks to discover our souls to express different feelings, making memories, fitting in different moods and actually to get to know more about each other while we are sharing so why not have a feature to connect the like-minded listeners. Here comes Spotify which can act as a matchmaker!
This feature could work according to the listener's location, following artists, recent discovery, favorite tracks, playlists in common, age and etc, in the discovery of where your potential soulmate based in.
This feature could be an amazing opportunity for listeners to get connected and hang with each other in real life. I already found this page (https://www.spotifymusicmatchmaker.com/) but I'm not sure if it belongs to Spotify or it's an ongoing project under the supervision of it.
