Spotify Wrapped for multi-user playlists. Solomon uses Spotify's track features API to compare the music tastes of users who have contributed to a playlist and generates a slideshow with those insights.

Solomon gives comparisons between the different users: whose music is loudest? Whose is most acoustic? Whose is saddest? It also works out the 'average' song from each user's contributed tracks. It's whitelist-only — ask for access!
