Anything off the "Grease" soundtrack. There's some kind of sensory-induced hypnosis (reference "The Naked Gun") that puts me into an instantaneous frenzy of violent anger when a note of that vile shit hits my ears.
I freaked my son out one day a few years back. I was walking through a store with him & my wife and one of those songs came on their radio. I went from totally chill to instant literal-red-faced flaming rage and my son hollered in the store "holy shit, dad!?!" I turned to my wife and said "I gotta get the fuck out of here. Now." and I damn near sprinted out of the store. Hopped in my vehicle and cranked some Slipknot to cleanse myself.
