Kanye West once bragged that he was “the greatest living rock star on the planet,” an egomaniacal opinion that is not shared by actual living rock star David Crosby, who appeared on “Watch What Happens Live” this week to do a little Yeezy bashing.

As the longtime member of Crosby, Stills & Nash (and occasionally Young) who performed at Woodstock, Crosby told host Andy Cohen that West “can neither sing, nor write, nor play… The thing that bugs me about him is the: ‘I’m the greatest living rock star.’ Somebody needs to drive him over to Stevie Wonder’s house right now so he understands what a real one is. Secondly, they should send him all of Ray Charles’s catalogue so he can learn how to sing.”

This isn’t the first time that Crosby has griped about Kanye. In a 2015 tweet, he characterized the rapper as “an idiot and a poser….has no Talent at all.”
