"Billie Jean" is a song by American singer Michael Jackson.
 It is the second single from the singer's sixth studio album, "Thriller" (1982).
 It was written and composed by Jackson and produced by Jackson and Quincy Jones.
 There are contradictory claims on the meaning of the song's lyrics.
 One suggests that they are derived from a real-life experience, in which a female fan claimed that Jackson (or one of his brothers) had fathered her twins.
 However, Michael Jackson stated that "Billie Jean" was based on groupies he had encountered.
 The song is well known for its distinctive bassline played by Louis Johnson, the standard drum beat heard in the beginning, the repetition of "Billie Jean is not my lover" towards the end of the song and Michael Jackson's vocal hiccups.
 The song was mixed 91 times by audio engineer Bruce Swedien before it was finalized, though he reportedly went with the second mix as the final product.
