Is there an existing extension for the following use case :
Alice, Bob and Carol want to listen to music together and agree to choose the music played one song at a time in rotation. They each choose their songs, either on separate devices (eg. phones that have access to the web interface), or by passing the device to each other in rotation. A kind of slot based approach.
I think https://github.com/Lesterpig/mopidy-party might have some base features to start off.
