Over the summer, Kanye West declared himself the greatest living rockstar on the planet and when Crosby was asked his thoughts on the situation he did not respond kindly. Crosby took to Twitter and called Kanye “an egomaniac,” “dumb as a post,” and said “he creates nothing.”

It seems the Crosby, Stills & Nash member still holds his harsh opinions against the rapper and once again addressed Kanye on Twitter: “why don’t you create something yourself instead of spewing more awful poetry over someone else’s work yet again.”

The outrage seems to be directed at the rumors of Kanye wanting to make a David Bowie cover album. There is already a petition going around to stop the rumored album from being made and we bet David Crosby’s name will be on that list. Check out his tweet and retweet in the gallery below.
