Even if so, that's a different claim from the content being political.

its not not-political

Sure, like Earl Gray tea is tinged by what you're listening to. It tastes a bit different if you have Beethoven on versus Miles Davis. Therefore, although tea obviously isn't musical, it's not non-musical, either.

Both the music and the tea are produced by and through market capitalism which depends on a particular configuration of the state to operate efficiently, ie politically. Its just the case that the most efficient configuration is also the one beyond politics.
