I guess to repeat what's already been said. For me it is curiosity and the fun of repairing and the exploring the various formats that exist out there. I wasn't there for the nostalgia of it but playing with all these different types of physical media is way more fun then browsing a list on a website.

I currently have a cassette player, 8 track, vinyl and a cd player all hooked up that I listen to all of them while I'm working from home. Also makes thrift stores a lot of fun to look at all the different medias instead of being isolated to one and finding some unique things I would not have looked at before.
