Just a weird thought i had. Music seems to get faster and more chaotic in modern days.
Rap music(nigger music) is the fastest "music" there is
And also if you listen to Edo Japanese music from a few hundred years ago its very slow paced , whilst Japanese 1980's Enka music is faster paced but slower than modern Japanese music, and modern Japanese music is faster paced than both Edo and Enka music.
So is fast and chaotic music a sign of a deteriorating society that is losing civility? Even Western classical music today is faster paced than in the past. https://archive.md/tvwM5
If you compare two very similar songs, people tend to prefer the faster-paced, higher pitched one. It feels "more exciting".
There's another element at play, hypnotic brainwave entrainment. Beats activate brain waves - 5 beats per second (300bpm) increases 5hz brain activity. They are literally using pop music as a hypnotic medium.
It may be the sign of a deteriorating attention span. It's very disorienting when everything in your environment is probing for your attention.
If you go outside of pop and radio, there's a lot of great music being made by artists who can reach an audience faster than ever before.
