The actual quote is: "“You have to remember I’m a musician,” said the singer-keyboardist who back in the ‘50s did as much as anyone to pry open the body of American pop and inject it with soul. “So rap doesn’t do anything for me; I can’t learn anything from it. Rap is like reciting poetry--I could do that when I was 7. All you have to do is match (the words) with the rhythm. That’s nothing. That’s [expletive]."
Who gives a crap what Ray Charles thinks or says? He was one musician who's prime was 25 years before the advent of rap. And he was an old fart when he gave that interview. You go ahead and shake your fist at the changing world.
And no, you couldn't "recite poetry" when you were 7. You could say the words but you need a lot of experience to know how to really recite a poem.
