Hmm, not really. I took a brief look at the UI during the Catalina beta and concluded that I wanted nothing to do with it. I have spent years learning how to use iTunes well. I'm not about to throw away that investment of time and energy on a new, untested app with a different UI. I'll stick with iTunes to manage my music library. Catalina will have to wait, probably forever.

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.
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?
