Playlist with the most listened songs for two people

So far, playlists can be “private”, “public” or “collaborative”. I know there are some “smart” playlists, for example, the playlist “Just heard” and the playlist “Top Tracks”. But I’d be great to have a playlist created with the most listened songs of two persons and be updated automatically along the time.

I know comparisons aren't good, but Spotify has somethinkg like that and it’s very interesing and fun having a music partner.
