I didn't use the music from the scene in which Godzilla dies in GODZILLA - KING OF THE MONSTERS for the one in which he does actually meltdown because Godzilla was not what I was trying to focus on this time. Instead, I tried to focus on the dark side of humanity, which lead to the creation of atomic weapons, and Godzilla.
