Taking music that was shitty thirty years ago and lazily running it through some pirated plugins doesn't make that music not-shitty.
No one cared about this music when it came out in the 80s, I'm not sure why anyone cares about it now. Any illusion of nostalgia is just being projected by the people putting this on bandcamp, or the idle minds running certain music culture blogs. In either case, it's coming from people born a decade after the wholesale-sampled music was originally put to tape. It's low-effort amateur-hour detritus. There's some kind of dementia involved alright, but it's not coming from the music. If I want 80s electronic dementia, I'll listen to the Akira soundtrack.
It's probably no coincidence that anything I've heard referred to as "chopped and screwed" has never lived up to that moniker. When you say chopped and screwed, I'm expecting Disco Hospital or The Anal Staircase, not low rate LA home studio pap.
