MusicBee on Windows has a plugin that achieves this. On macOS I can only find one (Album Flow), and it works only with my Apple Music library.

I’m looking for something that works independently, with a directory of music I point it to. Does anything like this exist today?

I’ve done quite a bit of searching, I hope I’m missing something obvious because it’s an extremely intuitive and accessible way to browse and listen to music. Thanks!
