I bought a used 6th gen Nano off craigslist this morning and it had originally been "swiped" clean. I asked to have one song added so I could hear it play when I came to pick it up - it worked great I created a playlist for my wife but I cannot download it onto the Nano. Under "Devices" it list this Ipod to "Taylor", the girl that owned it. I'm thinking when she downloaded that one song, it locked it back to her ID. How do I undo/reset this so I can download our list to it? Thanks.
