Well I know I wouldn't have the patience to watch myself play tetris for 37 minutes. I sometimes play along in my head when I watch these and, occasionally, am surprised by how often it does exactly what I would have done until I remember that I was the one that played it in the first place.
I think the sprint's more fun to watch because that's where you have to go as FAST AS HUMANLY POSSIBLE. I actually topped up my highscore today and managed 81.86 blocks/min... which is like, less than half of what the top players do ]:
