In the late sixties and early seventies, black music started getting political about discrimination and disadvantage. Often, it was a comment on social and domestic circumstances - like this:
Family Affair
Sly & The Family Stone
It's a family affair, it's a family affair
It's a family affair, it's a family affair
One child grows up to be
Somebody that just loves to learn
And another child grows up to be
Somebody you'd just love to burn
Mom loves the both of them
You see it's in the blood
Both kids are good to Mom
"Blood's thicker than mud"
It's a family affair, it's a family affair
Newlywed a year ago
But you're still checking each other out
Nobody wants to blow
Nobody wants to be left out
You can't leave, 'cause your heart is there
But you can't stay, 'cause you been somewhere else!
You can't cry, 'cause you'll look broke down
But you're cryin' anyway 'cause you're all broke down!
It's a family affair
It's a family affair
