Popular music is similarly time filtered, but the article/video is addressing contemporary pop music. If one listens to current pop, time has not yet taken its toll.
1927 is very late - essentially contemporary - when it comes to the history of music. 
History of Electronically Recorded Music was the intention.
Intention of what?
1927 was the beginning of modern electronically recorded music history, clearly not the beginning of music history. What we listen to on our fancy systems, regardless of the genre is basically new.
Yes, as I commented above.
I really liked the Truth video above . I’ve often wondered about quantifying the variety and complexity of music and giving it a rating so people could some what objectively understand what they were listening to.
The documentary The monster that ate Hollywood shows how decisions that were once made by a handful of studio execs based on intuition of whether a story was good or not was replaced by a corporate mentality regarding the marketing and cross promotional aspects. This is probably Similar in terms of how musical acts are chosen to sign and promote.
The goal has always been to make money, not to be good. Movie studios have become exceedingly good at making money.
The music industry is good at picking the correct acts for money making, but are currently having trouble monetizing their choices.
I just need to add that even great recordings and familiar material can and will in fact be perceived differently on different days. That’s our brain chemistry creating a perception variability that can’t be explained on a forum post, just will shorten by saying that our dopamine level is directly tied to those perceptions. Those who continue to analyze rather than enjoy may be decreasing the hormone itself which normally fluctuates. Listen, feel good, and stay within there. Because thinking is not feeling.
Many however derive at least as much enjoyment from experiencing music as a thinking, intellectual process as those who experience music as feeling.
This may well explain why I find most rock and other pop music tiresome, predictable, repetitious, boring. For me, there is little music there.
And is not meant to make fun of those genres, but pop as of last two decades is a dopamine depleter along with the biggest dopamine killer of all. Blue light. Yes, music can makes us think after listening to it.
Commercial rock especially in the last decade is top 40 pop music disguised as rock. Same time signatures over and over again.
As a child of the 90’s, I miss the sub genres and all the experimentation.
Would anyone suggest that Nirvana, Soul Coughing, Sublime, Mighty Mighty Bosstones, or Nine Inch Nails sound alike ?
I would say today’s rock scene is not diverse and moving in the opposite direction as originally intended. Today’s rock is not paving new musical roads, it all feels like another Avengers sequel over and over.
For me, good music does not make me think after listening to it, but while I am listening to it.
I do not find “today’s rock” any less compelling than 1960’s or 1970’s or 198o’s or 1990’s rock. I struggled sitting through Dark Side of the Moon a couple of times to try and appreciate the appeal. I made it through, but failed at the task. I have a couple dozen LPs and CDs of highly touted rock and other pop music of many decades which have similarly been played only a couple of times.
But I will listen to anything at least a couple of times to try and grok it.
I see, or I hear, no, I mean, I read what you wrote. I can relate a bit to your perspective, specially about Bob Dylan, as cerebral as the lyrics may be, the music portion is just absent of my enjoyment. Even Simon and Garfunkel can be exhausting if listened for too long of a session. They sound good though, in my opinion of course.
Huh, “grok”. I haven’t thought of that word in years. Thanks, Stranger.
Several very creative computer programmers I had the pleasure of interacting with through the nineties were fond of grok.
My primary enjoyment of particular music comes from the revitalization of the emotional connection to whatever I was experiencing in the past while listening to it.
There were a number of LPs that I spent countless hours at friends houses recording to tape to get it just right. I didn’t have a decent turntable and they/their parents did mind as they could see I was careful and purposeful in the process.
Rambling thread drift…
I understand, there are pieces of music which strongly evoke certain memories akin to Proust’s description of involuntary memory invoked by the episode of the madeleine in Remembrance of Things Past.
However, I cannot call the emotion/memory by intentionally playing the music. If it works, it does so with perhaps 10% vibrancy. But the unplanned, sudden hearing of certain music can be highly evocative. Fragrances and smells can do the same.
Just reading ‘fragrances and smells can do the same’ takes me back to a trip to Kapalua, Maui with a particular woman. Oh my!
