Currently I am a Spotify Premium user, I have 6 Echo devices in my house. If I am listening to Spotify on my mobile phone at any time I can go into the Spotify App and change the device to stream on and choose one of my Echo's/device groups. This is great, as it gives me control over my music and also when Alexa is being a bit thick and can't find the track I can just go into Spotify.
Now. I am currently considering moving over to Music Unlimited, because I am a bit fed up of Spotify only allowing 1 stream at a time. BUT, within the Amazon muisc app (on android) I cannot see any functionality to allow me to select device/which echo I want it to play on.
I have found that I can go into the Alexa app and do this, but honestly its at least 6+ clicks and each time it has to load etc, its not efficient, user friendly or engaging and this isn't what I want to have to do every time.
I want to be listening to a song on my device walk through the front door, go into the music app and just click "play on this echo/group"
