Marvin Gaye. Super Love. Got his Greatest hits prio to What's Going On & the rest of his discography after it.
The Supremes. Rihanna who? This chart topping machine is insane. Diana's heavenly voice, those melodies,... ah.
Otis Redding. Simply stunning. The voice, the delivery, the soul, the music overall... bye.
Aretha Franklin. No explanation needed, just say a little prayer for your faves.
Nina Simone. That voice, that pain...
Simon & Garfunkel. Those beautiful harmonies....
Sam Cooke. Pure soul.
Then there's of course
The Beatles... duh.
+ James Brown, Ray Charles, Elvis, Chuck Berry, Roberta Flack, The Temptations...
And that's only a portion of the 60s... Let me not get into 70s
