Spotify is preparing this redesign for free users

While there are several notable changes in this version of Spotify free for mobile, perhaps the biggest is the new option to play certain playlists on demand, as seen with the “Gold Edition” playlist above. If a playlist can only be played in shuffle mode, that is now designated with a blue shuffle icon. Previously on the free tier, all playlists could only be played in shuffle mode. – Dani Deahl, The Verge
