I've wanted a music player like the early versions of iTunes for a while, and this looks like it might fit the bill.

Those who've only known Music.app and later iTunes versions might be surprised to learn that there was a time when iTunes actually had a clean, intuitive UI: https://www.versionmuseum.com/history-of/itunes-app

Beautiful. I remember running iTunes 5 on my Powerbook G4, incredible how things have changed.

Interesting! Will be checking it out.
