Nightmare Nonexistent Song

What fear of singer, band, or musician and material haunts your dreams? What are you glad never was? Instruments, particular voices, genre of music, and a mix you thought of and never shared.

Example: Elvis Presley sings Nirvana’s Smells Like Teen Spirit. Thinking of The King attempting Grunge gives me cold sweats. His style and that song are oil and water. I’m happy it dies here.

I am haunted by The Band That Played California Lady’s heretofore undiscovered followup “Rhode Island Lady”.
