Kanye West criticized by Ozzy Osbourne, Donna Summer's estate for allegedly using uncleared samples for new album

Black Sabbath frontman Ozzy Osbourne, and the estate of the late singer Donna Summer, both publicly accused Kanye West of using recordings of their music without permission for the rapper's latest album.  

West's album "Vultures 1" — a collaboration with singer and rapper Ty Dolla $ign — hit streaming services early Saturday morning.

"Vultures 1" was previewed at the United Center in Chicago on Thursday night, and clips from the show proliferated on social media, teasing a song "Carnival" that Osbourne took issue with for allegedly sampling a clip from a 1983 live performance of the Black Sabbath song "Iron Man."
