Ok, we all know that disc 11 is a creepy and disturbing disc, but most people have tried to discover the secret to it by listening to the disc and they have failed, but a french player name "BSIdro" dug deeper he decided to get a visual look of the sound the disc made. He discovered C418's signature while analyzing it, he also noticed a creeper like face in it. He realized however that if he put herobrine's head on it, it fits perfectly. Most of you might be saying "c418 did that on purpose!" no he didn't because this music disc was added before this herobrine "rumor" became popular.
