Someone In The Dark : Recorded in September 1982. MCA Records was not to release E.T. the Extra-Terrestrial until after Christmas 1982. (This was to avoid the audiobook competing with Jackson’s new album, Thriller.) The song “Someone in the Dark” was not to be released as a single. MCA Records breached both conditions, releasing the storybook in November 1982 and giving 7-inch promo copies of “Someone in the Dark” to radio stations. After Epic lodged a $2 million lawsuit, MCA Records was forced to withdraw the album and prohibited from releasing “Someone in the Dark” as a single. Epic executives had felt that MCA was misleading members of the public into believing that the then-recently released single “The Girl Is Mine” was featured on the storybook album. The plaintiffs further requested that MCA Records be banned from working with Jackson in the future and that any other media owned by MCA featuring the singer be prohibited from release. As a result of the legal restrictions that prohibited the public release of “Someone in the Dark” as a single, the promo copies which were made have since become one of the singer’s rarest and most sought-after records; some have been sold for over $1,600. The song’s opening version was later included as a bonus track on the 2001 special edition of Thriller, as well as the box set Michael Jackson: The Ultimate Collection in 2004.
