lol dont be afraid.
when you get strike for such cases from individuals instead of companies or record labels, and since you already added some commentary, just dispute it on fair use grounds, its easier for yt to approve your dispute, in cases of individuals.
if they approve your dispute, then the rights holder will have some days to take you to court.
99% of people wont do that and its too expensive.
he wont do that, and the strike will get auto retracted if he does not.
just dispute him and done
