Is anyone seeing strange match behaviour. I only noticed this morning that out of blue all our iOs devices are now showing a lot of duplicated artists under the artist tab, also many entries under most letters for various artists. Songs that were supposed to be part of a compilation are sticking their nose in here too. It's basically all screwed. I immediately went onto the pc iTunes and checked the metadata, this was all perfect with spellings exact and album artist and artist consistent. I updates iTunes match, I disabled and re enabled match on the ios devices. But no difference. Its seriously screwed up. I have Adam and the ants (as an example) listed FOUR times with the songs randomnly spread across all 4 entries. Many, many artists are like this now. But in iTunes all lists perfectly and correct. I even tested our Apple TV and disabled and re enabled match, this displays everything perfect too. So it's iOS specific and affects all our devices phone and ipads. Just suddenly out of the blue. I think there is something messed up at apple with the cloud affecting the lists. Maybe the imminent apple music is screwing something up. Very frustrated and disappointed as I like match but I am not happy with this. Seems to mainly affect uploaded music from my own collection but for years and years its all been ok. And the metadata is absolutely spot on. No errors. I re edited a few carefully to be sure but it makes zero difference. No matter what there are many duplicating artists.
