It's all to do with playlists within iTunes, either a normal (drag and drop) or a smart playlist which is dynamic depending on what variables you use, plenty of info on Apples website, and the web in general just do a google on iTunes, playlists etc
Mood: Channel Swim is now a (bad) memory not a dream
Love mine, what a wonderful thing to have hundreds of your fav songs in a tiny little box. Limewire.com has thousands of songs and other things! Although for legal reasons I of course don't use it! When I first got mine, I had a great time going through all my old LP's and recreating memories in my ipod. Anyone who was at the DSC Awards night will have heard a selection as I made up a playlist and just plugged my ipod into my PA and pressed go.
