Also, the nostalgia is a cultural thing, rather than an individual experience thing. People that never lived the 80s, or this style, are also nostalgic of it, even tho they never lived it. This is an interesting sociological phenomenon.

Yeah, interesting! I've definitely started enjoying a lot more old movies/music myself even though they're before my time and I never watched/listened as a kid. But something about the style I like, even though it's outdated. So can definitely be an appeal to older styles even when nostalgia isn't a factor
