Lol. Nah nostalgia is fairly predictable. It's often a thing you caught a whiff of as it disappeared, that in your youthful lack of deep understanding saw the thing more in its idealized form, minus the flaws that build with experience.
Targets of nostalgia are kinda necessarily N-1 things, not often N-2 or more. Roughly speaking.
But there's a social component that makes it more fun -- participatory art of making things, vinyl, sleeves, new sounds, etc. Then the medium doesn't matter much at all.
After all it is recorded sound and THAT isn't obsolete.
If it gets you off, do it. Nothing is true; all is permitted.
