I don't know why iTunes is so confusing, but I have this problem where when I plug in my iphone, which I just recently restored and updated, itunes wants to add more music than my phone can hold, and won't allow me to change that. It shows "autofill" in the music tab of itunes and won't allow me to change that option. I just want to copy a few albums over to my phone. What am I doing wrong here? If I try to change any syncing options, iTunes also wants to remove EVERYTHING from my phone, which is so ridiculous.
