This seems like its something simple, but I've been trying for hours and I can't work it out. All I want to do is add a few MP3s to my iPod. No, I don't want a library on my computer synchronized with my iPod, and if I remove tracks from the library, they will also be deleted from my iPod next time I connect. Why would I want that? I just want to add and delete tracks at will. Surely there's a way to do it. I'm on a PC, by the way.
