I have my iPod mini set on autosync with iTunes on my iMac. I added ONE song today... one. I dock the iPod mini, and it updates six songs, songs that I recognize and never changed. I unplug the mini and think of a test. I add a song that's already on the iPod and in my library to a few playlists that it wasn't in before. I touch nothing else, and I plug the iPod back in. iTunes should sync the new playlists very quickly, and display no "Updating song x of x" because no songs are technically being synced. For some reason, iTunes syncs another song, a song I rarely listen to but I recognize. It is not the song that I just added to new playlists. A few days before I was listening to "Walk Idiot Walk" by The Hives. All of a sudden it skipped to the next song. I discovered that my iPod mini seemed to think it was twenty seconds shorter than it actually was. When I got home I docked it, and it updated 8 songs including Walk Idiot Walk. It ended at the proper time after that. What the hell is happening? iTunes keeps updating or syncing songs that were never touched and should already be synced. Walk Idiot Walk seemed to shorten by 20 seconds. iTunes updates new songs, but it also updates old songs that haven't been touched. I don't change ratings on the go, or anything of the sort. I only dock my iPod when I change a rating in iTunes, add songs, or make playlists. Let me try docking the iPod again and see what iTunes does this time. This time nothing changed. iTunes said "Updating iPod," then said "iPod Update Complete," without changing anything. However, more and more routinely, iTunes syncs random songs. It doesn't seem to cause any trouble, but I'm afraid the Walk Idiot Walk incident was caused by erratic autosync behaviour. Any idea what's going on?
