  * care about the non-premium video that could be swapped rather than the premium video that
  * was played.  This is because all the metadata is stored against the non-premium video.
  *
  * @requestParam string videoTitle The title of the non-premium video that could be swapped
  * @requestParam string premiumTitle The title of the video that was played
  * @return bool Whether the controller was successful or not
