I have a brand new iPod shuffle. Today I used it for the first time, then synced it to iTunes. Half the songs iTunes lists as having played today, did NOT play; and some songs that did play aren't shown. In other words, for some of the songs I played, when I sync, a different song shows as having played. I had the same problem with an older shuffle, but I had assumed Apple would have solved this by now. Is there anything I can do to fix it?
