Due to some complicated international restrictions, some 8Tracks playlists will not play by simply pressing the ‘play’ symbol. What you will need to do is click on the playlist’s title (e.g. Karen or Disco Essentials), which will open up another player. Click on the ‘play via Youtube’ button in the centre of the player screen and you’ll be right! I apologise for this ‘workaround’. The 8Tracks team are working to fix the situation.
