as_string

    my $str = $song->as_string( [$format] );

Return a string representing $song. If $format is specified, use it to format the string. Otherwise, the string returned will be:

either "album = track = artist = title"

or "artist = title"

or "title"

or "file"

(in this order), depending on the existing tags of the song. The last possibility always exist of course, since it's a path.

This method is also used to automatically stringify the $song.
