Such argument from authority. Very fallacy. Wow.
Seriously, saying "they're professionals, they know what they're doing" is possibly the worst argument you could make. Professionals fuck up all the time; if that weren't the case, there would be no such thing as a bad record, which there are plenty of.
Also, if we aren't allowed to complain about anything because "an artist makes music for himself", you have no right to constantly complain about AI. Of course, that argument is bullshit for reasons I shouldn't have to spell out, but I'll spell them out anyway: they're selling that music to us. If they're marketing music to us, we should expect to be pleased with the product. And if not, we have every right to complain.
