I have floppy disc copies of the original Civilization, Master of Orion and Alpha Centauri, presumably somewhere in storage, that I spent $60 each on back in the '90s. But I've also spent the $5 to buy digital copies from Steam, GoG, etc. so that I can actually play them today. I wouldn't have the first idea how to proceed in getting a 5 1/4" floppy up and running these days.
Same for music. I have a cassette tape of AC/DC's Back in Black. And a CD. And an iTunes download. No idea where, but I paid real money for each of them and thus, presumably, own them. In the car, I stream it from Apple Music. Just last night I was practicing guitar so I played it off Youtube, which appears to be the fastest way to get music to come out of a computer these days.
So yeah, when I pull out the old CD collection, I look back fondly to being able to rattle through them in the center console of the car and swap in a new one without ever taking my eyes off the road. (and having it actually play instead of invent some new form of bluetooth/cell communication error).
But in practice, I don't have a single cd in the car.
