Unifly Music leverages Spotify to allow friends (or strangers) from any location to listen to music - together. Users can log in and either join an existing party, or host a public or private party. Because the app syncs with Spotify, you can either have a "fresh start" playlist, or use an existing playlist that you curated in the past, while listeners can "co-DJ" and vote for songs to influence whether they stay on the playlist or not. It's great for offices (with people remote, or in the same office location), AirBnBs with friends, road trips, casual get-togethers, or anything needing music.
