I recently restored my iPod Nano and added about 6G of mp3s to it -- files I'd added in the past with no issues. Now all those files show up as "Other" instead of Audio, and when I try to restore it again I'm told that my iPod can't be restored because the files are "in use by another application." HUH? Is my iPod just wigging out? I tried resetting it and that didn't help. So now what do I do, just throw it away?
