Will Media Center 13 or 15 work with 4th generation nano? I purchased a 5th generation and CAN NOT get any music to show on the nano. Music shows that it has been transferred but when I unplug the nano, no music is on it. I just found out that Apple has done this purposely so that I have to use Itunes (Which won't load my 4,000 songs into it without crashing). SO, wondering if using an earlier generation nano would work and which one? Thanks Apple for wasting my time.
