Hi, I have an Amazon Kindle Fire and today my spotify suddenly doesn't play any music at all anymore. There isn't any indication of anything except that when I hit shuffle play, it just says get premium to listen to unlimited music. (that isn't exactly what it says, but something to that effect). Anyway, I just wanted someone to confirm with me here. Did Spotify suddenly change their policy with Kindle Fires or what happened? Can only Spotify Premium members use it?
