Support Spotify Connect to allow users to use the Spotify app as the controller.

Meanwhile, in the real world, Spotify launched the system with Pioneer as Launch Partner
Just a few days ago a microsite went live where you can see what alternatives to buy to get rid of your non-supported SONOS devices

Hi folks, There's not much to say at the moment but we'd like everyone to understand where we're coming regarding the announcement from Spotify. Sonos is a platform for music lovers and we want Sonos customers to enjoy all the music on earth from whatever source they choose. We have an excellent partnership with Spotify which is, and will continue to be, an important part of many of our customers music listening experience on Sonos. Thanks for your continued support.
I was very close to buying two Sonos Play 1s in the past few days and was shocked to find out that Sonos does not support Spotify Radio. Because of this I will not be buying into the Sonos ecosystem. I shouldn't have to go into a third party app (Sonos) to utilise features (or lack thereof in this case) of music streaming services. The relationship between Sonos and Spotify looks volatile at best and I'll be sticking with Spotify. Until you have more tightly coupled integration with Spotify I won't be investing in Sonos because Sonos is supposed to enable me to listen to my music. I'd be paying enough to not have to come up with workarounds and hacks to utilise features by Spotify to get them working with Sonos.

Please please please support Spotify Connect (and soon!). I imagine it's probably a case of releasing a bridge that has the compatible Connect chip.

Don't force us to use the Sonos app, you should improve the Sonos app to make us want to use it.  Then we won't be asking to play direct from Spotify which offers are much faster and sophisticated solution.

same here!
From my point of view Spotify app has a great UI, Sonos app doesn't... but you can arrange the different rooms and connect other music services. That's it. No more.

Please Sonos, integrate Spotify Connect!

Hey Dude,
I just bought my first Sonos and was planing to expand it. But if I cannot listen to my favorite Spotify radio, I do not see the point.
I feel very disapointed by your advertisement stating that Sonos support Spotify, which is by far exagerated.

Has there been any movement on integrating Sonos support into Spotify (via Connect or whatever other means)? The Sonos UI is a pain each and every time that I have to use it. Combined with complete lack of reaction from Sonos, I am just waiting to switch to some other solution the minute Spotify Connect expands to cover more devices...
(different Paul than the one above - but same frustration)

Sonos, I respectfully insist on an update for this. This isn't just a simple request by many of us, but a direct misrepresentation by Sonos. A timeline for your resolution or a true technical reason why this isn't possible should be provided. I invested a good deal of money in my Sonos system and until we receive that update, I will be reaching out to every tech review site through multiple means to explain how Sonos says it's "the best Sonos experience" yet doesn't even meet functional parity. How long has Spotify had Radio? How popular is it? Seriously, your false promises feel like dirty business tactics. I encourage all to share this thread through social media, by emailing examples to tech review sites and write reviews yourself on places like Amazon.com or for the Sonos app in the App Store.

previously I thought this may be related to some kind of hardware requirement but now that I think about it, it doesnt - I have an Iphone and Ipad which clearly dont have the required chip and they can act as 'Spotify Connect' clients.  Yes, they have the 'Sonos App' installed but whats an app other than a bunch of lines of code running on an operating system.  Since each sonos is effectively a little mini Linux computer Im sure with the tech bods could sort something out.

SOLUTION: I bought a small Century-branded Bluetooth receiver, no larger than a small match box in Akihabara, Tokyo. Plugged it into the line-in port of one of the speakers on my system. Works like a dream.

When I press the Spotify connect sign on my iPod touch it immediately does what I ask it to do. Stereo remains separated over two speakers and all the functionality of Spotify Connect is available.

Ensure that you have enabled the "automatically detect line-in" setting in the SONOS app. After that, you never have to touch the SONOS app again.

Sound quality is great and range, as advertised, some 10 metres. Cost: JPY 1800. Which is next to nothing.

Very happy - frustration gone. In addition, it works also for my Microsoft Surface with Windows 8, another piece of equipment/OS that SONOS does not want to provide an app for.
