This is a copy of an idea proposed here which was closed as being an issue (I do not agree but how can you argue on a closed idea)
Currently, if I want to control my Sonos system from the Spotify app I need to first play the first song, then select the target for the music, then rewind the song to the beginning.
This is a bit annoying, it would be much more user friendly if you could select the target and then start playback direclty on the chosen target.
Note that this does not only affect Sonos but all audio sinks that can be selected in the app, e.g. Chromecast or the Spotify application on my PC.
Sometimes the "current song bar" at the bottom above the tabs is shown although no song was started yet. In this case the GUI let's me select an audio target but then complains that I need to start a song first.
We're sorry for the confusion,
We’ll be sure to pass your suggestion onto the right folks here at Spotify.
If you think this is also something other Spotify customers would think is a good idea, be sure to add it to our ideas board. Those who also support your idea can then vote on it or add to the conversation.
