Title says it all really. I've got an mp3 parked up in a folder on my desktop. It can play through iTunes fine but I can't add it to my library so I can put it on my iPod touch. Any ideas what I'm doing wrong? I've manually dragged it into iTunes and it doesn't show up and I've also tried File -> Add To Library. Am running iTunes 18.104.22.168 on Vista SP2. Ideas would be appreciated! Thanks!
