Aside from the unhelpful "What?", that seems like DH4 Counterargument in pg's disagreement hierarchy[0], subtype "arguing against something slightly different from what the original author said".

Presumably "someone who makes music and sells recordings of it for a living", the people I was talking about, won't "feel as the gp". It doesn't seem like your criticism really touched on what I said.

(Maybe you are also assuming "No-one is entitled to make a living selling their music" or something like that.)
