No shade to the classical music enjoyers, I am one of them, but that is nowhere near a large enough market for the largest company in the world to acquire a niche app for the sole purpose of catering to them. It only makes sense to me if they’re after a tech stack that can be folded into their main service, and Apple almost always companies for their tech rather than their product (including Beats for Beats Music).
Rolling it out as a classical music app first is a pretty clever way to test new features and architecture at limited scale. I would 100% look to that app to see the potential future of Apple Music.
> because from their other products, they seem to be a company that believes in taking their time and delaying releases till they are done to a level that they deem satisfactory
This is definitely not the case for a long time already. Some people would probably say "Since Snow Leopard". If you use the Apple Music app on macOS, or really any recent macOS apps that was ported from iPadOS to macOS it's obvious that this is not true anymore. System Settings would be another such example.
