6. Marilyn Manson — 'Mechanical Animals'
As unsettling as Marilyn Manson's androgynous, gothic, Barbie-like nude body is on the front of Mechanical Animals, the album cover did not go unappreciated, landing on the list of The Greatest Album Covers of All Time. What's more, Manson's creepy look was fine-tuned by the pros. The prosthetic breasts were actually designed by the same people who created Darth Vader (George Lucas' Industrial Light and Magic).
