Forgive me, I am a week in to owning my first Sonos product, the arc soundbar.  When I originally set it up, I was able to use the Spotify android app to connect to the arc and play music.  I do not have a premium subscription to Spotify.  Today, I cannot connect and play music to the arc through either the Spotify android app or by launching Spotify through the Sonos app.

When Spotify first launches, you can connect to the arc but no sound will play.  If you fallback to the device you are using, Spotify will play music just fine.  When you then attempt to connect to the arc, the Spotify app will tell you that a premium subscription is needed to use this feature.

So my question is - has this changed recently?  A week ago everything was great.  Today I need a premium sub to just play music to a speaker over wifi.  This seems backwards in the extreme and a warning to everyone over DRM and subscription services.  If I buy a network speaker I would expect to be able to stream music to it over a wifi connection.  But the fact that these subscription services can just remove that ability any time they like, unless you pay up, makes the whole thing feel like a hostage situation!  

I am very impressed with the arc BTW.  I bought it to replace my A7000, sub and rears, which I did not like at all.  Music was very much a secondary consideration.  The sound profile is fantastic and I preferred it over the muddy waters of the A7000 immediately.  Just wondering if anyone else is in my boat (or is everyone just paying for spotify premium!)
