Is your feature request related to a problem? Please describe.

When someone outside our family account has been using our Spotify Connect device, playing from HA is not possible. The only workaround I found is to connect to the device with my Spotify app, which uses a family account.

Describe the solution you'd like

Transfer playback to device, regardsless of current status, so even when another account is playing.

Describe alternatives you've considered

I tried to switch the device off and back on via media_player.turn_off and turn_on. Unfortunately, my Bueasound Powernode does not support these services.

Additional context

None
