Almost the entire thing. How about keyboards having an integrated pause play button but it only works for Apple Music if it’s the last responder in handling the event. On YouTube? Hijacked. Incoming phone call and you want to pause music? Nope, your Mac ANSWERS THE PHONE! I was finally fed up and installed a 3rd party app that forces pause play to only hit Apple Music.
I use my MBP through a USB-C dock with an external SSD attached and whenever Time Machine or CCC triggers a backup my audio starts skipping. Sure, that isn’t Apple Music’s fault, but it’s part of the ecosystem and that kind of performance should be considered when designing the system.
And then the UI. All web views with click delay.
I like exploring jazz and electronic genres but navigating and scrolling to start one sub-genre takes like 30 seconds. There’s no way to pin genres that you like or hide genres you don’t care about.
I feel like my collection of music from 2000s is gone, even though it was uploaded to the cloud or something … through some apple program 10 years ago. I still have the metadata of my collection but even that is just a facade.
Maybe it's generational because I seem to be around the same age as you and I also hated the way my music collection "disappeared" into Apple Music (and a whole host of other things I disliked, chief of which that it keeps giving options for things you almost never want or need while at the same time it's hard to just, y'know, find and play and tag the music you want)
Isn't the play button issue solved by the Touch Bar? (I don't know because I don't use Apple Music yet), but I'd assume so since:
I just started playing a Youtube video and a Spotify song, then clicked on the audio button in the Touch Bar and it looks like this, double clicking the icon opens the appropriate app (opened that through the Control Strip, enabled in the Keyboard settings): https://ibb.co/6Pr1V6x
Though I guess the point is moot since the Touch Bar seems to be being phased out, and also due to the existence of 3rd party apps...
So, I think the pause/play button problem is almost unsolvable: I want the pause/play button to always pause whatever sound is currently playing and then resume it the next time I hit it. The issue is, though, I think doing this correctly in every situation becomes an exercise in telepathy.
