- To shuffle a playlist:
    - Settings > Shuffle = songs
    - select a playlist, BUT DON'T GO INSIDE IT...  go to the screen right before, where you view the playlist name
    - press the "play" button (the one at the bottom of the scrollwheel, labeled play/pause)
        - if you were previously playing a song, and it was just put into pause mode, then you'll have to hit "play" again

    The above procedure also works for the "All" entry under an artist
