Given that we're using the knob for Up and Down (rotating it) and Right (pressing it), it makes sense to use the large Menu button under the display for Left.
The "Random" button could logically be mapped to Shuffle, (as it is on the remote), but Shuffle is also available as a menu selection, so it is more useful for it to be Add to playlist.
