In older updates before the release of Chapter 4, the early version of the music sounds completely different and much shorter in length, only lasting for 36 seconds before looping in-game. They completely remade it in the recent update.
During the crossover mod Hello Bendy for Bendy and the Ink Machine, the track only plays in the ritual room when Sammy gets hunted down. This is because "Bendy" is replaced by the Neighbor who has a different chase theme.
From the mod for Hello Neighbor, this track serves as the Neighbor's chase theme when he spots the player.
The beta music can be heard playing in the "7 BEHIND THE SCENES FACTS about "Bendy: Chapter Three"!" video.
