ASMR just kinda means "pleasant tingling", and videos with asmr in the title tend to just be "neutral stimuli that I hope will make you tingle pleasantly." Mostly they're indistinguishable from "oddly satisfying" videos with the addition of, like, sensual whispers, or something?
I wouldn't be too surprised either way if metal melting in a forge wound up in either collection of asmr or oddly satisfying.
"Like reddit but not owned by a single company" is how I've put it.
