For a long time the only interface in iTunes that I've really liked was the Column Browser interface. That's remained available throughout the various changes in iTunes and now in Music over the years, but disappeared in Catalina.

Fortunately, that disappearance was only temporary. It returned in 10.15.2.

Select "Songs" in the left sidebar, and a "Column Browser" submenu will be added to the View menu. Turn it on (⌘B), and you get a nice, no-nonsense, high information density view of your collection, letting you quickly filter by genre, artist, and album. Right click on a column heading and you can add columns for composer and grouping or remove columns.

FYI, The column browser interface is back in the Music app as of the 10.15.3 Beta.

> I'm not about to throw away that investment of time and energy on a new, untested app with a different UI.

Come on, now. Think of the poor product managers, the struggling UX researchers and designers. How are they going to make their careers off of minor upgrades tied down to past investments of users?

When I was working at Apple, some of us had a saying: "Apple knows what you need, and we're going to give it to you – good and hard."

The new UI in Catalina is worse. You cannot view other albums when you have an album open, instead you have to click a button to go back for viewing all the albums again. I also think the music app takes way too much space of the screen for what it needs shown to function. Apple must not have anyone seriously working on it.

Speaking of that, iTunes Radio and Apple Music are TERRIBLE guis! The web-based column views are really limited and crappy. You can do so much better with web GUIs if you want to, but Apple just wanted to waste a ton of screen space.
