I have 2 identical mirrored, machines running, home and office. Both happened same day. OOpps. But, if you play a radio station downloded with the link from the original station, these play. It's only the stations dragged from the Apple pick lists. I think they inadvertanly reassigned links in coding.
I have seen small coding issues that were corrected after mistakes by update programmers who didn't test the software updates completely. Apple is probably the best at quality control, but I remember one case where they had to roll out an update (note they don't call it a patch) in a week to correct a .jpg preview problem. Not sure if it was an overzealous legal team issue or what.
Mysteriously seems like the same thing. In the last case, It would pop up with a permission statement each time, even if it was your photo. After calling, they said, dah, it must be me. Waddya know, 1 week later it was fixed. No pop-up.
Could this be just what KMurph81 said. always about money? I think Apple introduced a "softfart." A fart in the software. Hopefully this too will pass, without much smell.
