McCartney explains in a recent interview with John Wilson for BBC Radio 4’s Mastertapes how Winfrey advised him to pass on the popular track.
"I get this track back, a thing called 'All Day.' He's taken my melody and he's made it seriously urban, which is funny because the lyrics use the N-word -- a lot!" said McCartney.
The iconic Beatles singer said he got a bit of push back about being on a song with that kind of language.
"People like Oprah, who's a little conservative about that stuff, said, ‘You shouldn't do it, even black people shouldn't use that word,'" the rock legend continued. "I said, 'Yeah, but it's Kanye!' And he's talking about an urban generation that uses that word in a completely different way. It's the context. So I was actually pleased with it."
In addition to "All Day," McCartney talks about working with Kanye in the studio and compliments the rapper's creativity, which according to McCartney, "inspires [him]."
"I love Kanye and he loves me," McCartney said. "He's a monster -- he's a crazy guy who comes up with great stuff so he inspires me."
