uses the database to create random playlists of specified size
with the advanced GUI you can..
set the number of songs (up to max playlist buffer)
set the number of tracks before a repeat is allowed
play the tracks when finished

were corrupted
-- Incremental loading for very large databases, allows decent speed and lower ram usage
