Multiple playlists?

I’ve had my 8gb clip zip for a couple of months now and I still can’t figure out how to make multiple playlists. I’m using MTP mode and I use Winamp to make my playlists. I’m not using any cards and I’ve dragged and drop everything into the player. Whenever I create multiple playlists, all previous playlists to the last one created will be empty. Any suggestions?

Don’t use MTP mode. Use MSC instead. I have several playlists I can select at will that were created this way in Winamp.
