I watched the 1st five minutes and gave up. The episode was, to my mind, clearly set up for cross promotion rather than the "topic". The lack of depth in researching classic two chorders along with Shill being there and Ms. Spender is yet another mutual admiration society meeting.
There're plenty of two chord songs to love and enjoy particularly when vocal harmonies or even original melodies create new chords or voices.
