Is there a way to randomize play on the entire playlist? So far I seem to be only able to randomize on a sub folder (genre in this case). Just curious. Thanks.

Turn on "shuffle" by pressing the 0 key on the remote control. The screen should respond with either "shuffle on" or "shuffle off" depending on whether it was already activated.

The, press the "menu/ok" button on the remote control three times.

Now all of your playlists are playing shuffled.

(You can also do all of the above from the player's main menus with the front panel).
