The background music?
He had them cut the background music in the beginning of the first one.
And it’s really the second and third videos that have the best commentary.
I know—I don’t know why it kept playing the first time around. I reloaded, and when he told someone to turn it off, it was no longer there.
People really need to pay attention to this guy! (but I doubt the ones who need to listen really will................)
