With the current beta build I noticed that Spotify has been having issues with the UI it doesn't update the song being played. The App will still play music but the display will not change and it will be frozen on one song You can still cycle through the tracks in the sound will change but the display will not.
As issue involves a 3rd party app, fix needs to be performed from the application side. It would be best if you let app developers know of this issue through their support channels.
