There are many things about the current commercial environment for music production and delivery that are not mentioned in the video that you can make a solid argument for being worse. The clear-cutting of the royalty system to screw over artists using streaming as the machine is awful. The loudness wars are a sad loss too.
But he's not talking about these things, he's talking about the absolute artistic quality of current music. If music makes someone happy, and they enjoy it, that should be the end of the story. I don't like hyper-produced, auto-tuned, click-tracked pop for the most part - but I do like some, and I don't fault anyone who does.
I think it is a unalloyed good that music production has become more and more accessible to people from all walks of life, not just a fortunate few who get an expensive record advance and get into an expensive studio. And, if streaming weren't raping artists royalty streams, I would find it equally unobjectionable. Wasn't this the promise of the internet, all knowledge and art at our fingertips? We actually got it for music, at least for a few years here.
I have access to streaming, but I still spend most of my time listening to complete albums in sequence, unshuffled - mostly things I've purchased in the last 3-6 months. His point about the difficulty of saving up for and selecting and buying music 30-40 years ago is a circumstance worth remembering and explaining, like a boomer's explanation of a rotary dial phone to a Gen Alpha, but not one to privilege or be nostalgic about.
