And the design as way harder to master than it should be. For instance, to search for a track in Apple Music, you have to be in any tab except iTunes Store. OK, there's some logic to it, but it simply is not intuitive. Why can't there be something that specifically says "Apple Music" that makes it obvious that that's where you go to find tracks? I'm an experienced computer user, and in fact a software developer, and when I first purchased Apple Music I was mystified about how to search for a track in Apple Music. I had to Google it. My wife, who isn't used to Googling for these kinds of answers and isn't a technologist, has no choice but to ask me or the kids how to do things like that.
In the Music app iOS, to make it show only the tracks you've downloaded, you have to click on the pulldown where you select Artists/Albums/Songs/etc. It's a switch on the bottom of that pulldown. When you're thinking "What tracks do I have downloaded?" this is just not obvious. When you get used to it, it's fine. But if you're a naive user, you really have to have a friend who's an experienced user just in order to figure out how to do such basic things. Naive users may not even understand that the Artists/Albums/Songs/etc. pulldown is a menu. And even if they know it is a menu, it's not intuitive to think that there's an on-off switch for showing all songs at the bottom of it, which relates a fundamentally different concept.
It all just seems like really poor design. I don't know what their problem is. But my son, who has always been an Apple user because I've been one, and who is applying to colleges like MIT to do engineering, is seriously considering switching to Android so that he doesn't have to deal with so many bugs. (Not that I know that Android is better.)
