• There are 16 in the final game.
• There are 16 songs in the OST marked with tildes (~) being one at the beginning: ～古えの地へ~ (~to the Ancient Land~), one at the end: ~残されし者たち~ (~Those Who Remain~) and 14 while battling the colossi: ~巨像との戦い~ (~Battle with the Colossus~).
• Retroactively, people make videos of SotC hypothesis about the myth of Nimrod being tore in 16 parts and scattered across the land to never be rejoined.
