I think he means, why should he have to predict what he might want to do this with, before using the empeg, rather than deciding on the spur of the moment, 100 miles from the nearest emploded computer, that he'd like to shuffle the playlists as described.

That is, it's not the increased disk usage of doing it with emplode that is the problem, it's the design of the player software that doesn't allow you to do this when just sat at the unit.

I think that's the idea, anyway. It does seem reasonably easy, from a layman's point of view, to implement this - some kind of 'only playlist' shuffle option.
