Q: wow, you predicted the length of your next video to the second! how did you do that?
A: it must have been already done at the time i said that. i actually could have also known it many days before, because the timing of all audio was finalized by the time the song production was finished, but, still i don't recall ever actually checking the run time until i was asked recently, and by the time i answered that, the entire video was indeed final
