The guitarist is not a fan of heavy rock and he cannot understand the appeal of the genre's top acts.

He tells the New York Daily News, "(Rock music) sounds like a dull thud to me. For most bands, getting the syncopation is beyond them. It's endless thudding away, with no bounce, no lift, no syncopation."

He continues, "Millions are in love with Metallica and Black Sabbath. I just thought they were great jokes."

Richards' disdain for musical genres also extends to hip-hop, with the rocker insisting he feels the music has little substance.

He continues, "Rap - so many words, so little said.

"What rap did that was impressive was to show there are so many tone-deaf people out there. All they need is a drum beat and somebody yelling over it and they're happy. There's an enormous market for people who can't tell one note from another."
