MP3/WMA playing order
When selected for play, Album Search, Track Search, or for Album
Select, files and folders are accessed in the order in which they were
written by the CD writer.
Because of this, the order in which they are expected to be played
may not match the order in which they are actually played. You may be
able to set the order in which MP3/WMA are to be played by writing
them onto a medium such as a CD-R with their file names beginning
with play sequence numbers such as "01" to "99", depending on your
CD writer.
For example, a medium with the following folder/ file hierarchy is
subject to Album Search, Track Search, or Album Select as shown
below.
