Does anyone know of a plug-in/work around or what have you to try to create sub-playlists in either iTunes or iPod? In other words, instead of making a "kids" playlist on my iPod, with every single wiggles/disney/sesame street song in it, and instead of making a separate playlist for each (one for wiggles, on for disney, one for sesame street) I could make a single "kids" playlist, then choose a sub-playlist (wiggles, or disney..you get the idea) to get to the particular songs. It would be VERY handy to be able to make a "classical" "jazz" "kids" "classic rock" etc genre playlists, with individual groupings underneath.

Thanks
