Hi Guys,
this idea just ocurred me, maybe its already a functionality that I do not know. Would be great if it was possible to sync the music/playlist that is acutally playing on two devices of the same family, For instance, to leave one devide in one room, and another device in the other room and the music played would be the same. This oculd work with different family members of the same account.
It's a very interesting idea. Right now we have something similar, a playlist called "family mix", next to friday releases.
