Certain songs continue o automatically sync to my iphone 5S
I am trying to remove all songs from my iphone but certain songs keep automatically syncing to my phone. I delete them and the list is clear but as soon as I select sync they come back. They are also seen in the list as a light grey, not bold like other songs I might add to the list. And there is a circle to the left of the check mark for the song selection. How do I stop these songs from automatically syncing to my iPhone?
iPhone 5s, iOS 8.3
