#3 GeneratePlaylist() case SONG_ORDER_DISC

[Scott Presnell]

I was having much trouble understanding the playlist
generation operations
as I was using them (posted about it in the Help
forum). But I eventually
figured out what was causing me pain. It seems that
in GeneratePlaylist()
song_order==SONG_ORDER_DISC is a special case handled
in a way I don't get.
The patch below removes that special handling of
SONG_ORDER_DISC (which I
often select, because I can always randomize playlists
later).

If anyone could comment as to this special case in
GeneratePlaylist, I would
be interested in hearing an explanation on how to use
it as it was intended.
