I do subscribe to iTunes Match and no matter what I do I cannot clear these greyed out tracks from my iPhone. I have turned iTunes Match off so I could delete them which I do but then when I connect my iPhone the greyed out tracks appear again. The tracks show as a stream and there is no size to them. I did download them to my iPhone via iTunes Match but obviously when I turn iTunes Match off and deleted them but they reappear. Short of restoring my iPhone I don't know what else to do. Any ideas?
