Okay, so I've seen a few greyed out songs in Apple Music before, but not this before. Pete Yorn's new album came out recently, and I've been listening on Apple Music. But a week or so after it came out, two of the songs (Summer Was a Day and Shopping Mall) became greyed out, and I can't play them now. Today I noticed a third song (Halifax) is greyed out. I see this on both my iPhone, and my Mac. What gives?
