How do I delete playlist icons?
At the top of a playlist there is an icon next to the playlist name. I know how to change that icon, but the list of candidates that I've created is getting very large and I need to remove some. It can't be done via the iTunes interface. So where are they stored on my computer? If I can find that place, then maybe I can delete those no longer needed.
