Every time I plug in my iPhone to manage my content manually, I can see a bunch of songs being pushed to my device. These are not songs that selected but they are just randomly being added. I see an autofill button but there is not on/off option. When I click the 'Settings' button next to it, I deselect 'Replace all items when autofilling'. But when I close iTunes and reopen it, the same thing happens. About 75 songs are cued up to be synced to my device which means my phone is always at capacity which also means I get all kinds of errors when I try to take pictures because I am out of memory.
