Did you actually watch the entire video? I agree that some of it is crap, but some of it is actually very interesting. One of the more interesting points was that most of the hit songs from the last decade were all written by the same two people. Another was the heavy-handed use of dynamic range compression. It is not all snobbery.
Music is a business. That's the answer. Massive dynamic compression sells. It isn't the producer or label who are to blame for giving their customers exactly what they want. Same for the song-writers - two of them seems to have been really good at creating exactly what the public wants to hear. That's an open marketplace. Generally we are all snobs on this forum by complaining that musicians, producers, and labels are making high selling songs. Zappa wrote a long allegory in the inner sleeve of this "You are what you is" double LP where he told the story of how really horrible cheese is all the food industry will make if everyone only buys really horrible cheese. He was making that point in the early 1980s, and now we are whining about the same thing.
And I am one of the whiners.
But this it is totally not fair to blame anyone but the customer. There are thousands of amazing songs and albums being released every year which do not have the negative characteristics we all bemoan in hit music. If the customers would buy all that stuff, it would be more famous and be heard on the radios and streaming stations and used in movies and TV shows. Intead, we refuse to buy anything great because we have decided our favorite records from thirty to forty years ago are perfect and anything which sounds different is shit, so fuck it all. Look at Van Halen - huge fans who abandoned them when Sammy Hagar took the front-man role whined for several decades that they wanted a reunion with David Lee Roth. Well, it happened and an amazing album was released which could very easily been that album all of the super-fans wanted to hear after 1984, but it was only modestly received and got limited airplay. It was a fucking amazing album and was exactly what Van Halen fans were demanding for decades!!! But the customers responded with a huge "meh."
Basically, we are like a bunch of old men in the 1960s whining that rock and roll is shit and nobody is making great music like Woody Guthrie, Burle Ives, and Les Paul. This is on us, not the industry.
So, I am getting tired of all the extreme nostalgia for the Beatles, or the Stones, or Led Zepplin, or whomever. That was great at the time, but there is some amazingly good stuff being released right now which is very worthy to stand up next to those old artists. If you were around in the 1970s when some of these classics were released, you'd remember all the shitty music being played on the radio - especially the top stations which were often NOT the rock and roll stations we look back on with nostalgia. Anyone remember the Carpenters, The Captain and Teneele (?), Tony Orlando and Dawn, The Osmunds, and so many other relatively shitty artists? Sure, we can look back and appreciate that stuff now, but at the time we hated that shit.
