Trivia[]
The animation might be a reference to the music video of the Tenacious D song Tribute, where a human guitarist (Kyle Gass) and singer (Jack Black) defeat the devil (Dave Grohl) in a song contest (the "Rock Off Challenge") for their souls. This is also depicted in the film.
It might be a reference to Beelzeboss (The Final Showdown), also by Tenacious D, in which the phrase Rock Off is actually mentioned by both Jack Black and the Devil.
It may also be a reference to the song of the Charlie Daniels Band song The Devil Went Down To Georgia, where a boy named Johnny battles the devil on the fiddle in a bet who is the best. The devil bets his golden fiddle and Johnny his soul.
