He was promoting his upcoming solo album, "Crosseyed Heart," which comes out on September 18.
But in the course of the interview, he had some pretty harsh things to say about rap music and heavy metal too.
Here are some excerpts, from Rolling Stone...
On rap: "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."
On heavy metal: "Millions are in love with Metallica and Black Sabbath. I just thought they were great jokes."
He even took a shot at the Beatles "Sgt. Peppers" album, calling it "a mishmash of rubbish..."
