If anyone from Apple cares to listen, I recommend just having the choice between “Apple Music” or “Library” remain on whichever one you chose last. That way you can continue spamming us with Apple Music because we will still see it every time we search for something, yet you don’t create an annoyance.
Or just go with what should really be done and make Apple Music a separate app. If you want to please your shareholders, focus first on making products that people love. Some of us have a lot of music that we have collected over years and can’t afford another subscription service. We save our money to buy Apple products because we know they’re reliable and are the best. It’s a slippery slope, so please don’t go down the spammy path. What are we going to have to move to Linux-based phones at some point?
