"Apple Music sucks for creating playlists" doesn't mean "Apple Music is a usability nightmare."
The entire industry is aware of the fact that user-generated playlists don't actually work to achieve mega-scale consumption. If they did, Spotify would be at 200m global subscribers and we would all pay for enhanced playlist features. People don't actually know what they want to listen to, and they don't want to spend time on curation -- not even on time curating their curators.
Spotify was built on the false premise that people wanted a "social jukebox" and that this "social stickiness" would somehow create an experience that, when combined with licenses to every track possible, would create an experience superior to pirated channels. Look, they'd say -- you can now see what your friends are listening to, and enjoy unparalleled social discovery! Better still, you can simply subscribe to their playlists and ride off their cool vibes!
The vast majority of people just don't care about this stuff, and definitely not enough to pay for it. They want to press play and skip stuff. And that's about it. The Pandora UI is the UI to beat. Everyone in the business knows this -- hence why you see everyone pushing radio metaphors over playlists.
If you're judging Apple Music on the basis of its playlist UI, you're an edge-case user judging edge-case features. Time to reflect on the fact that you aren't the target audience.
