From the horse’s mouth
Spotify has introduced a jukebox-style party playlist function for their Premium users. This feature, known as Spotify Jam, allows other people that the user invites to contribute songs to a “master playlist” from the other Spotify users’ own accounts.
The host account has to be a Spotify Premium user but the participants can use any Spotify account class.
The host sets up a Jam playlist by either tapping on the “speaker” icon at the bottom of the screen of the three-dot option menu within their favourite currently-playing playlist or song. They are then given the option to “Start a Jam” and determine which Spotify endpoint they have the music coming through, including audio devices that are Spotify Connect endpoints.
If you are on the same logical small network as a device that is running a Spotify Jam session and you start Spotify, you will be invited to join that Spotify Jam playlist. You can use a Bluetooth link to invite other Spotify users by tapping their devices together with the host device. There is also the ability for the host device’s user to show a QR code that users scan to join the Spotify Jam. There is even the ability to send a link via email, instant messaging, SMS or a social network’s in-platform messaging to invite people to the Spotify Jam.
Everyone connected to the same local logical small network can participate in the Spotify Jam no matter the account class. But Spotify Premium users can join from other networks, which may apply to setups involving mobile broadband networks, public access networks or the like.
The Spotify Jam feature is effectively a party-wide song queue where each participant adds songs to that queue. They can also see who added a song to the queue as well as contribute a song themselves. They are also exposed to a song-recommendation list that is generated by Spotify’s content-recommendation engine based on what is already in the list.
The host can also see the active participant list for the current Jam session queue list. But they can delete tracks or change the track sequence which can be handy for changing the party mood. For example, you may want to run with slower music at the early stages of the party then, perhaps play some upbeat floor-filler dance tracks after dinner when it’s time to dance, then subsequently run with more slower music towards the end of the party as the guests leave.
It may be desirable for Spotify Jam hosts to convert the queue list in to a playlist so as to have something that reminds them of the party. But could I see the Spotify Jam party-music playlist functionality appear on other online music-streaming services like Tidal, Apple Music, Deezer or Qobuz?
