 7.21.18  1:14 pm is it not because it's a power of two? I mean, 2 is arguably much more "powerful" and "magic" and 1 is pretty special, in the other direction 8 is a bit less "powerful and magic" than 4, 16 is a bit less, 32, 64, etc.  on a semirelated note, what do you think of so-called 'irrational time signatures' where the 'denominator' is not a power of two?  like 7/12 (which would denote a bar of 7 eighth-note triplets, because a whole note divided into 12 equal segments is eighth-note triplets) useful notation tool or pretentious bullshit?
i think in the case you referenced, most of the things they mentioned seemed to get their power from the lowness of the number. like less than 10
