I put Ozzy's original vocals over The Acacia Strain's "War Pigs" cover 

Not an AI cover but here ya go. The Acacia Strain's cover of Black Sabbath's "War Pigs" but with Ozzy's original vocals. Tracks isolated using UVR. Some parts sound kinda scuffed, I tried stretching some of Ozzy's vocals to make them fit better but I decided against doing that.
