ZUNE\0Music\01\0{0} - {1}\0TRACK_TITLE\0TRACK_ARTIST\0TRACK_ALBUM\0zune:ZUNE_GUID\0
 
// TRACK_TITLE: Title
// TRACK_ARTIST: Artist
// TRACK_ALBUM: Album
// ZUNE_GUID:  A GUID that may refer to the Zune device, Zune account, or Zune software itself.
 
// Note:  {0} - {1} is the format of how the string should be displayed in WLM - I ignore this entirely.
// Note2:  This method is used by other software, so I don't gate on ZUNE for the sake of maximum flexibility.  
// Note3:  The "1" after Music specifies the playing state.  0=Stopped, 1=Playing.  I ignore this and instead just use whether or not the other fields exist.
