John,
  How very strange... I guess it could profile the song or possibly this
information or something like it is stored someplace in the file, possibly a CDDB
or FreeDB (?) reference id is stored.  Not sure what else it could be or even how
as it was bounced through several difference programs... I wonder if there is a
field for cover art URL in there someplace.
