To be fair the glorified babysitter wouldn’t require 4+ years of education on educating children, so they probably couldn’t just be “simply teaching.” This is still an awful idea, they seem to be trying to save money by paying a glorified babysitter a lower wage than a teacher. Private schools can be for profit in some place, I wonder if that applies here.
I’m not sure when you were using it, but Navidrome definitely let’s you play individual songs and shuffle.
