As a long standing Spotify Premium Subscriber, I like many other's am extremely disappointed that Spotify have as yet failed to make the Spotify Radio functionality available to SONOS users.
This issue has been ongoing now since at least January 2013 in the IDEAS section of the Spotify Community forum, see link below:
There is also a similar discussion on the Sonos Community Forums, see link below:
I would like to get all of those users from both Spotify and Sonos together in order to petition Spotify to implement what should be a relatively easy feature, that ALL other Music Services seem to have been able to provide to their SONOS users.
Please help us to unify our efforts and get Spotify to add the Radio feature to the Spotify Service on Sonos by signing and sharing this Change.org petition.
Many thanks and best regards,
