itunes sync
I am using windows 10 and an iphone 6+. I am trying to sync my new music onto my phone, but am getting the message in the pic attached. What are my options? If I erase and sync, will that screw up the photo files on my computer? I am at a loss as to how this has happened.... if this only affects my itunes library, I should probably to this, right? Also, I have been having to manually download my songs from the cloud on the phone. I would like them to just. be. there! Am I missing a setting somewhere? Thanks!
