Damn, I thought I had something going there. <grin>
Well, it would seem to me that a layer of abstraction would help here...
Shuffling the playlist doesn't require reading the names of the files until
they are played, correct? Simply knowing the number of total items in the
playlist is enough to shuffle - we're only messing with the order of play.
So we simply pseudo-randomize the order of entries based on their indexed
location (16, 1504, 957, 423, 1100, 2) and read the entry name and location
when required (again, back to that semi-arbitrary 20 number). When the
playlist encounters another playlist during preload or loading, it will take
the time to process that playlist when necessary and index it in the same
Of course this depends on being able to locate items in real-time based on
an index number corresponding to their position in the playlist. I don't
know how difficult that would be, but I imagine it could be done.
What do you think, would that work?

How else can we make a full-playlist shuffle? We need to get them all and
