Yup I just left. I'm now on GPM and actually the audio quality is way way better on it, really supprised. Only thing I miss is the Spotify interface... But its music, I listen to it not look at it! a bonus is my car recongises the app better so I can navigate all my playlists in my car head unit, so better than Spotify there as well. So long Spotify, you snoozed on the wear app, so I'm out and moved to skynet!
I really hope Spotify will implement offline playback for AW2 devices soon. Looking forward to run and listen to music without tethered phone when I receive my preordered AW2-watch later this fall. But if Spotify fails to deliver I will have to jump ship and go with GPM.
