1. “Mercy, Mercy Me (The Ecology)” by Marvin Gaye
Silky smooth and effortlessly eloquent, “Mercy, Mercy Me” features on soul hero Marvin Gaye’s 1971 landmark album What’s Going On—itself a concept album addressing the woes of society. “What about this overcrowded land?” sighs Gaye, “How much more abuse from man can she stand?” Last word goes to the man himself, from an interview with Rolling Stone: “In 1969 or 1970, I began to reevaluate my whole concept of what I wanted my music to say.… I was very much affected by letters my brother was sending me from Vietnam, as well as the social situation here at home. I realized that I had to put my own fantasies behind me if I wanted to write songs that would reach the souls of people. I wanted them to take a look at what was happening in the world.”
