The Youtube Algorithm must be recommending similar videos to the both of us as I started getting the same kind of content a few weeks ago. I'm pretty partial to the Ace of Base "I saw the sign" cover that it's been recommending.[0]

It would be neat to see a humanoid robot feed the tape into the machine and press play and then have the camera zoom out to a bunch of robots dancing together.
Something about robots dancing to music that's produced by a mechanical MIDI machine feels right. Like a prelude to the impending replacement of humanity.
