I have a trial of the family premium plan and am confused how best to setup shared devices, like the Alexa app. I would like every family member to have access to their own music, and also allow multiple family members to use the Spotify Amazon app as a remote when music is playing on an Amazon Echo. Additionally, I would like to be able to start music for the family, and then leave the house and listen to Spotify in my car. As I understand it, initiating music in my car would stop music playing in the house (on the Echos) if I use my logon on the Alexa app.
FYI - I use several Amazon Echos around the house as a poor-man's Sonos system. The kids also have Echos in their room, and it would be cool to allow them to play different Spotify music in their rooms, while I listen to my music downstairs.
It may make sense to create a special type of logon for shared devices, like Sonos or Amazon Alexa/Echo. Maybe it already exists and I am unuaware. Maybe this is just a pipe-dream.
