In the Netherlands Spotify is now available. You may need to update the LG WebOS version first to instal the Spotify app. A shame you cannot cast songs from your Spotify Smartphone app. If you want this, I suggest you buy Chromecast (only €35). With the Spoticast app you can cast songs from your phone to Chromecast. This also is the case for Soundcloud with the app My Cloud Player.
SAME ISSUE I HAD, IM FROM GUATEMALA WHAT I DID IS THAT I CHANGE THE COUNTRY (USA ) AND THEN TRY AGAIN TO INSTALL SPOTIFY, WEBOS ASK ME TO UPTADE THE SOFTWARE AND AFTER THAT I WAS ABLE TO DO THE INSTALATION OF THE APP. THEN I CAHNGE TO MY COUNTRY ONCE AGAIN AND IT WORK! THE LG APP STORE IS AWESOME IN OTHER COUNTRIES IN MINE YOU JUS HAVE A FEW THINGS YOU CAN BUY. KIND OF SUCKS !
