iTunes: Organize Playlist Here is a quick tip in order to help keep your ever growing playlist to a minimum while viewing them in iTunes. We will be creating folders then moving the playlist into them even can be done with your smart playlist as well.
If your looking for a more automated way of doing this then I recommend using a apple script from Doug's Apple Scripts for iTunes. I will provide the link to it via his site.
