Rocker Ozzy Osbourne has called out rapper Kanye West, whom he said is “antisemite”, for using a sample of his music without permission and said that he wants “no association with this man.” Osbourne took to Instagram, where he shared that he had denied the request for a portion of a 1983 live version of the Black Sabbath song, War pigs to be used on West’s new album.

However, he claimed that he heard it was used anyway during a listening party. The rocker wrote on Instagram: “Kanye West asked permission to sample a section of a 1983 live performance of Iron Man from the US festival without vocals and was refused permission because he is an antisemite and has caused untold heartache to many.”
