It's Been So Long is a 2014 fan song by The Living Tombstone inspired by Five Nights at Freddy's 2, following the Purple Man, later identified as William Afton, and the mother of one of his victims. Spanish-speaking fans know the theme as the canción del hombre morado, a name that keeps circulating on soundboards and in edits. Unlike a FNAF Jumpscare Scream, this excerpt is used for story and mood, helping the song remain a shorthand for Afton lore years after its release.
