How do you stop iTunes from automatically adding songs from purchases online and songs that have been deleted from the iPhone. When syncing, songs that I had already deleted will try to re-upload itself back onto the phone. So far, I have tried unchecking boxes of the songs that I have been deleted on the iTunes library itself. I have resorted to immediately jumping to the "Songs on this Phone" tab and selecting all the greyed titles (with the loading circle next to them) and deleting them before they jump back onto the phone.
I run a PC, Windows 8, with version 126.96.36.199 I use an iPhone 4S
