In iTunes and on your iPod it is impossible to sort your playlists other than alphabetically.

To sort your playlists you could just use punctuation marks, but a more interesting way of doing this is using hearts, stars and musical notes, which the iPod can also display.

Using the character palette, under International System Preferences and also accessible through the Input Menu, these symbols can be found in the Miscellaneous category of the Roman lettering. These don't just have to be for sorting your playlists, they can jazz them up too!

The iPod can't display more complex symbols, however this is actually even more useful. It leaves a blank space, but still sorts your playlists into the order of the symbols, meaning they are sorted in your own order, but without anything before them.
