Shuffle/Unshuffle: Tapping the Shuffle button shuffles the playlist, changing the
order in which the audio files are played. Each random order is different. The
button changes to the Unshuffle button.
Tapping the Unshuffle button restores the playlist to its default, unsorted order
(alphabetical by the Title). The button changes to the Shuffle button.
If an audio file is currently playing, tapping the Shuffle or Unshuffle button does not
change what is playing.
Playlist: Tapping the Playlist button displays a menu that allows you to select
a specific item to play. At the top of the playlist is the Shuffle Playlist or Default
Playlist menu item. These menu items shuffle and unshuffle the playlist in the same
way as the Shuffle and Unshuffle buttons.
Close: Tapping the Close button closes the audio player.
