We need to be careful about selling all our CDs and vinyl just because these streaming services have taken over. There are several scenarios that could happen like musicians taking their music off the streaming services or the streaming services raising their rates to exorbitant levels. Once the streaming services think they have a monopoly, that's when rates might start to rise. Also, I couldn't listen to Neil Young for a long time except for what I had purchased because he wasn't on Spotify.
Granted, one of the best things about CDs was the ability to listen in the car and most new cars don't even have an option for a CD player anymore but remember, when you have a streaming service you own nothing but when you purchase a CD or vinyl, you own that music. Just stuff to keep in mind.
