         *       a. If current media item is the last one. The first music item in the list will
         *          be prepared, but it won't play until user press play button.
         *
         *          When user press the play button, the speed will be reset to normal (1.0f)
         *          no matter what the previous media item's playing speed is.

         *       again and play automatically. (The reason to enable auto play here is for
         *       testing purpose and to make sure our designed API is flexible enough to support

         *       current media item will be replayed in normal speed.
         *
         *    C. MEDIA_ACTION_REPEAT_NONE
         *       a. If current media is the last one. The service will be closed, no music item
         *          will be prepared to play. From the UI perspective, the progress bar will not
         *          be reset to the starting point.
         *
         *       b. If current media item isn't the last one, next media item will be prepared,
         *          but it won't play.
