Turns out, CDs are pretty durable. Even though my attic gets crazy hot in the Texas summer, none of the CDs (some 35 years old!) failed. Next thing I needed was to buy a CD player (again). I was somewhat surprised by how few companies are still making players, but I got an Onkyo unit that I'm happy with.
Now I have a pretty great sounding setup and I have little booklets to examine while I listen. Browsing the collection for something to play is fun.
I'm back to buying CDs and it's actually a great time to be buying this stuff. New and used is cheaper than ever (lots of stuff is the same price it was 30 years ago) and so much stuff is available online and off. I love going to Waterloo Records in Austin and flipping through the stacks to buy a couple titles from my list and probably another title or too because I liked the artwork on the case or the guy at the counter recommended something.
I also bought a small bookshelf system for my desk because popping in a disk then having some music for maybe an hour then having to get up to change it works well for me. If I'm streaming from Spotify I end up working for too long, often unproductively. Taking a break every hour or so and shifting my attention (take the dog outside, make some tea, change the CD, then back to work!) seems to help my problem solving skills. I look at it as a healthier version of a cigarette break.
The only problem I've had with my disks is that a couple of them seem to not be balanced perfectly and they make a bit of mechanical noise in the player as they spin.
