Yes, "Timothy" is on the list of all-time great songs about cannibalism; in fact it might be the list. "Yummy, Yummy" was by the 1910 Fruitgum Company, a group made up of studio musicians. I think revenge was the motive.

I can't imagine a worse song than "I am Woman" (hear me roar, though I'm such a crashing bore) by the inimitable Helen Reddy. Although "For All the Girls" by Willie and Julio Iglesias is right up there. And the list goes ever onward.

FLASH!! I think I've just discovered my "special purpose" in life. I'm going to write a song that is so-o-o-o-o bad that it ends discussions like these forever. It'll have to be sincere. It'll have to be timeless. It'll have to make children dance, women cry, and grown men go "oh sh*t". And it'll be a smash hit. Sorry, I gotta go. I'm on a mission that may last a lifetime. If anyone has any suggestions on what I should put in my song (although I won't really be writing it, I'll just be the vessel), maybe we can start another thread.
