I said second worst. She Wants Revenge is easily, by far, the worst cover on the album. I really like Manson's cover a lot. Fiona Apple's is tied with Manson's in my eyes.
Manson did exactly what a good cover should do; he stayed respectful the source material, but made it his own without crapping on it.
Panic at the Disco's version is the same fucking song just with their obnoxious voices instead of the Disney cast.
