Well, I hope this isn't sacrilege around here, but: anything I've ever heard by the Kingston Trio. Unfortunately, my dad had a fondness for them when I was little. I still haven't recovered!

Also due to my dad, "Slack Your Rope, Hangman." He thought that what I'm guessing was the PP&M version was a suitable lullaby. He would croon and I would go into hysterics until my mother stepped in.

Not sure if this is the title, but "Ghost Riders in the Sky"... another one I was terrified as a toddler.

For sheer annoyance, "I am Woman" tops my list. On the other hand, I'm secretly a fan of "Leave me Alone (Ruby Red Dress)," "Delta Dawn," and "Angie Baby."
