It's Been So Long was released in 2014 by The Living Tombstone as an unofficial fan song inspired by Five Nights at Freddy's 2, following their earlier viral FNAF track. Sung from a grieving mother's perspective, it became one of the most shared songs in the fandom and helped define early FNAF music on YouTube. This short guitar version strips away the vocals and keeps only the haunting tune. It is often paired in edits with the FNAF Jumpscare Scream for contrast between sorrow and horror.
