For me there are a couple of issues that make this release awful.
1) The entire left panel is now a giant hot button for the last-used tab, so when I'm clicking, trying to bring the window to the front, I end up navigating away from the current album to "New", or "Home", with no way back to where I came from. This is absolutely infuriating, and is worse than all the other issues because it happens over and over when trying to foreground the window when just a tiny part is showing.
2) The miniplayer lacks a button to add the current track to my library. I can make the playlist visible, and then I can add the *previous* track, or the *next* track to my library, but not the current one! This is the most backwards design ever.
Were it not for (2) I could use the miniplayer instead of the mess that is now the main window, but they even broke that workaround.
I also find the play controls at the bottom of the window nonsensical, though this combines with the general lack of configuration available. I can't collapse the left side-bar. I can't choose where the play controls go. I can't make flexible decisions on what I want in the mini-player and main windows, and I can't hide tabs I don't want like "New" or re-order the ones I do want.
I also no longer have an Info option for the entire album, so seeing album art is painful. This should never have required going into info and then viewing Artwork. Double clicking the album art should show it full-size... seriously, this is basic useabilty stuff and Apple just makes it worse with each release.
The "pod" that comprises the play controls is actually quite good. I wish I could make that float and use as a kind of mini-player, as it will at least let me add a track to my library.
I don't let Apple Music anywhere near my old iTunes library of purchased songs. That was always a horror show. As such, I don't have library size performance issues, but the app is still *incredibly sluggish* on an M1 Pro with 32GB of RAM and nearly a TB of free disk. I'd imagine it was a scam to make you upgrade, but people with the latest Mac don't get any better performance.
Buttons have zero-feedback and don't respond immediately, and transitions to any tab except "New" seem to take forever...
But oh, it's so good at showing me the "New" view I *never* want to see, in a hope I'll suddenly develop a taste for whatever pop Apple is pushing today – which I never will.
Finally, there are broken "dead" items left in the menu, such as "Show Status Bar" ... I wish I could show it, but that item did nothing at all, until the latest update that grayed it out instead, which is only slightly better.
Could we at least get a hotkey for "go to current song" - maybe a button for it that sits in a consistent place and doesn't require opening a drop down?
Apple's updates to Music have failed to be improvements since the point it stopped being iTunes. It ought to be easy to make a fluid, responsive, configurable music player because there is a huge user base. Instead, we have something that feels like a browser app made with a clunky web-framework running in a window and pretending to be native.
If Apple aren't going to take this app seriously, why don't they do a proper job of opening up an API so that others can do it right?
