I also found some significant melismas in "Danger Zone."
"Late" in the line "For we could leave it much too late" is sung with a melisma (E D) for a sense of degree (for "too"). "Lives" in the line "All of our lives" is sung with a melisma (although it's the same pitch twice: A# A#) to portray something of the entirety of that "all." "Go" in the line "And it's hard to know we should let it go" is sung with a melisma (G# F#) for a sense of (metaphorical) movement.
