Keith Richards has taken a swipe at Sir Mick Jagger's songwriting skills.
The 72-year-old rocker doesn't care that his Rolling Stones bandmate has already penned 40 new tracks for a potential new record as he would rather do something "really interesting" than be as "prolific" as the singer.
He told Uncut magazine of Mick's 40 songs: "Being prolific don't mean s**t.
"I've got three songs and they're dynamite. I don't want to make any decisions about this until the record comes out because I think it might change Mick's attitude, it might change mine.
"I want to see the fallout from this record before I decide whether I want to record 40 of Mick's songs or whether he wants to sit down with me and record some songs together. That's my thing. That's my ball there.
"I've got a few songs on the back burner and so does Mick - he writes a lot. I don't.
"I tend to concentrate on two or three really interesting riffs or ideas, rather than being prolific."
And after returning to their roots with upcoming blues covers album 'Blue & Lonesome', Sir Mick is now keen to take the band in a new direction.
He said: "I was writing last night at the end of the baseball match.
"I sat watching the World Series, playing my guitar. But I think it would be nice to do new songs and go in a new direction with them."
