"Lady Evil" is an example of a song that gave Ronnie James Dio and Black Sabbath a reputation for misogyny. "Digital Bitch," from the Ian Gillan years, is another one.

Similarly, there is no Heavy Metal song called "Satan's 666 Pentagrams of the Antichrist" by Lucifer's Choirboys - but wouldn't it be cool if there were? Anyway, Dio himself asserts in this interview with HM Magazine
that it's all an act! Isn't that right, boys and girls?
