I made a small modification to the WPS code. I usually have WPS set to
display id3 info, but I have a few songs that do not have valid id3 info
in them. So I made a patch that will use directory/filename to display
on the screen if there are no valid id3 tags. I also modified the
directory parsing code so that both

Genre/Artist/Album/Mp3_file

and

Artist/Album/Mp3_file

directory formats should work and display the proper artist/title.

This patch will only affect the Jukebox, but I'm sure it would be easy
enough to add to it to give the recorder the same behavior.
