Aside from the sentimentality of it, what really interests me is the economic differences. If you buy something on physical media, the fee to the artist is paid, regardless of if one ever listens to it. Alternately, if I listen to it a lot, and then sell it to someone who then also listens to it a lot, the same single fee is paid. Unlike streaming, the number of times a track is played is completely decoupled from the fee the artist gets. But the streaming companies pay such a tiny fee to the artist that it's basically nothing, unless you can scale up to a huge factor.

Meanwhile, I pay Apple a fee that is essentially what I might have spent on a CD every month to get all-you-can-eat access to their catalog. My fee doesn't change depending on how much I listen. I could keep the music going 27/7, or never use it, and the fee is $10.99/month. Actually, I pay a bit more than that for a family plan where 5 people enjoy the same access. Does my nephew and sister actually use it? Do my parents use it? I have no idea, but they can. I had to laugh that my dad, in his 80s, was frustrated when he was trying to buy a jazz album and he couldn't figure it out. I had to explain that he could listen to anything on Apple Music at any time for free, like Netflix.
