What is the most times a word or phrase has ever been repeated consecutively in an English song?

Question

Like as in "Boom" by System of a Down, they sing "Boom" 12 times - "Every time you drop the bomb you kill the god your child has born / Boom / Boom / Boom / Boom / Boom Boom Boom Boom Boom Boom Boom Boom Every Time You Drop The Bomb"

Answer 1

wasn't there a wonderful recording of "Ain't no Sunshine when she's gone" where Santana repeated the phrase " and I know" 24 times in a row without taking a breath in between?
( I remember counting and trying to sing as long as he did. Not easy)

Answer 2

theres an "oh" song...thats the only word in it.
