Anyway it turns out if your library size is bigger than the capacity of your iPod, it will create a new playlist to hold a selection of your library for the iPod. That’s all fine and good but what about the songs already on my iPod?
So I removed all the songs from the playlist that I didn’t want and was prepared to just reformat the iPod hard drive.
But it turns out that the iPod _only_ keeps the songs that are on that playlist. Everything else got deleted away. In this case, my only source of irritation surrounding the iPod has been appeased.
