"Enter Sandman" was the second music video from Metallica. It was also the first of six Metallica music videos directed by Wayne Isham.
"Enter Sandman" was the first song written for the "Black Album," but the last one to get finished lyrics.
The song follows the theme of childhood fear, in nightmares, with the eponymous Sandman symbolizing the sleep that he dreads. However, the Sandman of European folklore actually represents the bringer of good dreams.
The lead single from Metallica's commercially successful self-titled album (commonly known as The Black Album), "Enter Sandman" was certified platinum, selling over 1 million copies. The song was Metallica's biggest radio hit and it's considered their signature song.
