Whenever I try and use Autofill to add any recent additions to my library to my iPod, it always seems to remove about the same, if not more songs than it puts on. For example, I added another 3 albums to my collection last night, and just went to add them to my iPod. Press Autofill... 'This will add 43 tracks and remove 285 tracks' Why? It's not like the iPod is full up or anything. It also doesn't show what it's removing. Anyone able to help?
