I had the same question; I assumed it was a typo.
I associate cultural appropriation with people who cut and paste the aesthetics of something without having a clue about the thing they’re jacking. E.g. the proverbial kid at the festival wearing a war bonnet.
The whole appropriation conversation gets kind of overwrought, IMO. (And I say that as a card carrying, far-left leaning sociologist who does fieldwork in Latin America and has had this conversation too many times to count—just to qualify that statement). Not to derail this poor OP’s request for some metallophone samples…
