Speaking from the point of view of a complete novice when it comes to mp3 players, I assume that when you've got a squillion songs on your Ipod, there is some sort of cataloguing system so you know where to find something. How complex is it? Unlimited playlists? Folders? How does it work?
Yes, I tried the Ipod FAQ. but it starts a couple of rungs above my knowledge level, so be gentle with me here.
