	When it does fillSongsFromSonglist(), it just creates a list of Track 
objects. But track objects can be just an actual music track, or a 
reference to another playlist (if their index number is negative). 

	Have a look at Playlist::writeTree() which recursively calls itself if 
it gets negative numbers.
