<< I listened to it a few times, and I think it just sounds like Jeremy's
voice cracking.>>
Listen to it many more times. At about 5:08, there's a sound that is
something other than his voice. Between the words "hit" and "hard" (where the
"me" should be and there is instead a half-me). It almost sounds like a
microsecond of a DJ "scratching" a vynil record. Listen with good earphones
or do what I do and press your nose against a good speaker with your hands
cupped behind your ears to get the full effect!
