#aster's chatter

Thundersnail*: the part with the drums kind of sounds like burn in despair

ASGORE: the section with the heartbreak motif (0:34) follows the burn in despair rhythm; the first bit of the section with the determination motif is also a partial callback

Rude Buster + variants: the beat throughout most of the song sounds like the burn in despair pattern (easier to notice in vapor buster since it's slowed down)

Checker Dance: the drums use the burn in despair pattern; it's most audible when the first pitched instruments kick in and follow the rhythm

Spamton*: it's the rhythm for the second half of each bar. i'm not so sure about this one, but he does have dialogue referencing "burning eyes" so it's still very possible this was intentional

(also, it sounds even more like the burn in despair motif in AIRWAVES when they repeat spamton's motif over and over (minus the half-beat-early start every other bar))

Giga Size: it's there once the pitch instruments and drums kick in

Paradise, Paradise*: this, too, contains burn in despair (...and so does SOUTH OF THE BORDER!!*, but it also sounds like Cool Beat/alarm_titlescreen/something you'd randomly come up with so i'm not sure. it depends on how silly toby felt when composing it)

Black Knife: immediately starts with the raw motif. this is the most obvious one by far

BURNING EYES: also immediately starts with the raw motif, only very slightly modified
