That’s actually something MediaMonkey [0] (Windows-only) had for a long time (I assume the current electron version as well, I use the last native version). Classical is one of the defaults, but you can add whatever.
It’s one of my favorite pieces of software, a true music library manager and not a music player with some management features tacked on.
