The song “The Sound of Silence” by Paul Simon & Art Garfunkel has very powerful message because it is timeless and can be interpreted by each person, according to their own conscience.

Almost a decade ago, metal group Disturbed recorded a more emotional version compared to the original folk version, and this version highlighted its message even more. Written in the 60s, under the influence of the great increase in entropy that the world was experiencing with the cold war and other not so cold wars, with the cultural revolutions around the world and the new scientific discoveries that would take man to the moon and others not so pleasant situations. The lyrics in its third paragraph say something as current and profound as the voice of vocalist Dan Donegan from Disturbed:

​“And in the naked light I saw
Ten thousand people, maybe more
People talking without speaking
People hearing without listening
People writing songs that voices never share
No one dared
Disturb the sound of silence”

At this moment, it appears that humanity’s entropy is well above average, we urgently need more silence, moving our energy towards rationalism and meditation. My humble opinion.
