Music rooms allow you to play music for your teammates as long as everyone participating has Spotify premium.
In order to participate in music rooms, everyone will need to integrate Spotify in their Tandem preferences.
Creating a music room
To set it up, create a new room and toggle the Music Room option. Then, join a room and start playing Spotify.
DJs and listeners
The first person to join a music room will be a DJ. You can always see who the DJ is by looking at the main app. You can also see the current track they're playing in the main app.
Tandem synchronizes a listener's Spotify player to mirror what the the DJ is playing in real-time on their computer, the DJ isn't actually streaming music through Tandem.
This means that anyone can adjust the volume of their Spotify player independently from the rest of your team, without changing the volume of the Tandem call.
If the DJ wants to make someone else the DJ, hover over their name in the lower left hand corner of the call box.
How to listen
When joining the music room after the DJ, open your Spotify player (can be desktop app or on the browser) and push play. Tandem will then take over your Spotify player to synchronize it with the current track the DJ is playing.
Note: sometimes there may be a delay of up to 10 seconds before a listener's player is synced with the DJ.
