My latest geek-out thing is my iPod. I found at smartplaylists.com a description of a playlist called 101.5 KPOD, which I’ve adapted for my own use. The point of 101.5 KPOD is to sort of emulate a radio station rotation of your own music. It focuses on highly rated music that you haven’t heard often, and my additions clears out some of the cruft and also throws in some new stuff. Read on for a description of how to set it up.
