Isn’t fundamentally the issue that for any symphony by Beethoven or whoever that there are thousands of recordings of performances? So if I decide I want to listen to a certain one then I also need to pick a particular performance that a particular orchestra did a certain time?
Apple Music has a totally separate app for classical music. It was specifically designed to address exactly this.
For each composer, it shows all their well known works, and then you can tap on each to see all the recordings of that particular piece.
Smart move on Apple’s part, if you ask me.
