Worst individual track ever: "Mommy, Can I Still Call Him Daddy?" by Dottie West. It's available on CD, although I have the equally shameful LP (higher fidelity lousiness). This song is spectacularly, staggeringly bad. Worth buying as a torture track for those guests that just won't leave. Even my dog hates it. Close runner-up: Ewok Celebration, by Meco.
Worst Music of All-Time
What is the suckiest, pots and pans clanging together, cat in heat, fingernail scratching on the chalkboard noise you have ever heard? To me it has to be all that MTV promoted, yo-yo-yo, B-boy pop music that seems to consume the airwaves, magazines, and television time. And by all means feel free to bash particular artists, I like that too. Example: You could find more musical talent in the restroom of a trailer park chili feed than on a Puff Daddy album. Not too far off, huh?
