You can still put CDs onto your laptop and phone, and still download things such as Spotify for use when you have no signal.
There are all sorts of issues with providers being able to amend, delete and lock content, including the way that (for example) there’s going to be no decent archive of early computer games soon as the companies stop supporting the activation servers, but you can still do what you want with your CDs.
DH bought me a beautiful Technics turntable for Christmas, and I’m very happy to be able to get all my old favorite albums on vinyl again.
