By moving away from streaming services, you can once again own what you bought and paid for. Algorithmic playlists are nothing, nothing at all compared to the loss of ability to use your own player, edit your files, back them up, or not be nickel-and-dimed to get around artificial restrictions. Not to mention that with streaming services, music can be taken away from you after the purchase.
One can have both: use the streaming services to discover new music, buy physical media of the bands you like most. Not everyone has this option, but it is an alternative.
