In a interview with the New York Daily News, Richards expressed his dislike for Rap and hip hop, deeming them for "tone deaf" people and consisting of a drum beat and somebody yelling over it.
In the same interview he called Metallica and Black Sabbath great jokes and bemoaned the lack of syncopation in most rock and roll, claiming it sounds like a dull thud to me.
He also said he stopped being a Beatles fan in 1967 when they visited the Maharishi Mahesh Yogi.
