Everything follows patterns of the irrational number, and the result is a mind-blowing progressive rock song. This expands upon the concept first tried with the Golden Ratio song. Notice the length of the video?"

We human have got 10 fingers, so what? That's not an intrinsic mathematical property of anything, it's just arbitrary.
It might have been less arbitrary if they'd also chosen to subdivide the octave into 10 tones, but nope, they used the also-arbitrary 7-note scales based on the also-arbitrary 12 semitone subdivisions of the octave. So they could have used base 7 or 12, not 10, and I would have had fewer complaints. Of course even using base 7 gives them the freedom to just arbirtarily chose different keys or modes during the different phases of the song, meaning that yet again you were hearing their conscious artistic choice, not an intrinsic property of the number.
Did you also notice that in the Phi one, the first phi-ratio split of the string on the fretboard was actually at 2-phi not phi-1 (so they threw away the larger proportion), but the subsequent splits they threw away the smaller portion. Why the difference? Arbitrary!
Math-metal is just reverse gematria.

The 12-TET is far from arbitrary. Read up on the history of scales, and you will see that there was no lack of conventions on how to create them. See this for instance [wlonk.com]:"
In other words, 12-TET is both mathematically sound, and outlived nearly every alternative ever devised.

Why 1%?
Why not 0.979534234987976 percent?
Seems pretty arbitrary to me.

Sorry, I didn't use the full quote, it ends with:
The 12-TET is a local minimum regarding the approximation to the ratios, the next best approximation is the 53-TET (with 31 and 41 coming close). They are, however, full of dissonant intervals, so most of the notes would never be used anyways. The 1% is not an arbitrary choice, it just happens to be within 1%, all near possibilities are much worse than 1%.
