I feel like this has been missing in more recent videos though.
One thing I often notice is that if you listen to music with other people, you hear new things in it, because you are partially hearing it the way they do through reading their reactions.
Song writing is an art it's not like a technology where you can point to power usage and how v 2 is better than v1 to show the thing is now better, great.
He goes into great detail about the entire songs it's never just "point to a thing" and say "there it is". He'll describe how the choice of the wording, the chords, what scale e.g. "mixolydian vs dorian", how it all combines to make the song great.
He's at his best when he's analyzing the vocal melody against the chord harmony (ie: they're using the #4 on the F for a Lydian feel to the 3rd on the Am)
