I found a British pop song so catchy and so utterly execrable, it killed a FIVE DAY LONG earworm of Pat Benatar's "We Belong."
I'm not sharing it. It's too dangerous. All other music may become extinct if it is released to the public.
But I'll give you hints: it's based on the Moroccan's children's game "A Ram Sam Sam." The video involves a lot of brightly colored vinyl. And it's really... just not very good at all. It's just the musical equivalent of 20 mL ivermectin. :O
