Nope, only one playlist per keyword. Boolian math between playlists causes the generation of a temporary list.

OK, I thought you meant that you can do this already with the current playlists.

This way the keywords are not properties of the music itself. That is a good thing. We should be able to share playlists, even if we can't share music.

You need to store this metadata somewhere when not on the empeg and have emplode automatically pick it up, for the reasons Tony gave below. A standard place already exists - ID3v2 tags. Nothing stops you from sharing that data - CDDB already does it for most tags (I just wish they included the year).
