Order of Play
Tracks are played in the following order:
•Play begins from the first track in the first playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.

continues sequentially through all tracks in each
folder. When the last track of the last folder has
played, play continues from the first track of the
first folder.

the filename is not displayed.
