I much prefer endomusia to aurivermiphobia. I've never heard anybody say they were frightened by the song stuck in their head.

And oof - earworm / ver d'oreille - NOT the description I'd choose. It sounds squishy and full of suckers that keep it glued there.

And NO I am not afraid or disgusted by worms. But usually, worms that inhabit bodies are not the nicest looking things. Not like your basic brown earthworm whooping it up in the earth loosening the dirt and helping roots thrive.
