Those who love harmonious voices in popular music know it is missing in today. It was extremely popular in the sixties.
I invite you to find great harmony and meaningful lyrics on the current top forty list. https://www.at40.com/charts/top-40-238/latest/ You cannot!
Why did harmony leave the music scene? Those of us who have ever sung in close harmony can tell you that it is not easy. Members of the group must be able to read the musical scale and then sing those notes. Harmony requires singing voices that complement each other. Vocal discipline is demanded; the voice of the lead singer cannot run away from the voices of supporting singers.
If you miss hearing great harmony, try these.

Additional Note: Perhaps we could borrow the principle of musical harmony and apply it in life to slow the rampant division that has overtaken society.
