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.
