For the last few days, the sort order in Artists view in my iPhone and iPad Music app has been acting strangely. There are multiple instances of some artists, with albums split among those instances. For example, I have about a dozen songs by the Stylistics, and they're now divided among four instances of Stylistics. Also, some artists aren't where they should be. One instance of Warren Zevon is under W, as it should be, but another is under D. Also, today, scrolling through artists lags and stutters. I'm guessing that this is a temporary glitch related to the upcoming launch of the new Apple Music app, but I haven't seen any other posts about this problem. I have iTunes Match and the latest version of iOS and the Music app. Anyone else experiencing this?
