Not to say that I think modern pop is anything special, but how do these three categories of measurements correlate? How do you compare something like Dr. Dre's 2001 to Led Zeppelin 3 with only these measurements? I would imagine that 2001 would rank lower on these metrics, but I don't think anyone would describe it as "worse".
The TV series Westworld had a scene where they had Shogun era musicians playing a Wu Tang Clan song on traditional Japanese instruments. https://www.youtube.com/watch?v=__DEAK3AinM
Yeah, that sounds right. There are some producers that can stand on their own though too, but they would probably do well in the metrics in TFA.
When a piece of music is both simple and captivating, I view that as a huge achievement. I can play simple songs, but no one wants to listen to them (and rightly so!). The Ramones can play even simpler songs, and they are special. I have no idea how to measure something like this.
It's shocking how if you take a song from a genre that is focused heavily on vocals and take out the vocals, it's not a very interesting song anymore. I think rap -> poetry is a more common conversion than rap -> orchestral music because the latter is just crossing too big of a divide between music styles.
