Professor Diana Deutsch has done pioneering work on the cognitive processing (or MIS-processing) of auditory input. One of many of her amazing findings that became eponymous was that words on repetitive hearing like with a stuck record can become perceived as music. She published in the 1990's BUT I tried out the top movie quote memes and 1) they all work and most spoken words DO NOT and 2) the background score is IN EXACT TUNE TO THE MELODY OF THE SPOKEN WORDS. I do not have an explanation of how that happens.
