I agree it's a difficult problem to solve in general. But I set the bar much lower. I'd be happy if I could a) search by label (or limit the results to a certain label, for non-classical folks that is Decca, Deutsche Grammophon, etc), and b) instead of seeing 6 tracks all named "Requiem in D Minor, K.626:3. Sequentia:" be able to tell which one is the "Confutatis".

This really doesn't take that much and it isn't an impossible goal. And yet Spotify wasn't able to implement these two things for years, even though people keep begging them to.
