Genetically Modified Music (GMM) is outfitted with unnatural modifications that radically alter the natural pitch of singers to make the product seem more palatable to consumers, much like a watermelon without seeds is created to be less annoying or a banana is cloned to make corporations rich. That unnaturalness is why no one eats those two things.

Over time, this genetically modified music residue accumulates in our brains and there it has an even more unsettling characteristic; advocates fear it is dynamically compressing our minds. Every time you listen to genetically modified music (GMM), those inserted genes produce effects called intonation consistencies in every cell.
