y'all are gonna hate me for this, but:
noise as a genre, to me, is mostly navalgazing pointless treading of "avant garde" waters that have been tread before that are more fun for the musician than the listener. messing around in the hopes of making a neat sound and stopping there rather than applying it anywhere. its the purest distillation of improvisation to the point where it loses any point or internal logic besides "i am making". and going off of what aen said, noise is more or less what we make music from, and just arranging it makes it music. for a cheap and probably inaccurate comparison its like abstract expressionism and early surrealist techniques, but instead of developing an internal harmony, its usually some UCLA conceptual jerkwad too far up his own ass to realize that its really easy to see that you're half-assing it. noise as a genre is often a picture someone took of a spill that looks cool, or a sketchbook full of old and retreaded abstract ideas.
not to say that noise can't be musical, or be used in music while still retaining it's noise-ness. theres a shitton of artists who do that, but i'll point to Disco Inferno for what i mean, specifically.
most like... noise-noise music is visually similar to like this
an ad hoc utilization of various improvisational and creative techniques ultimately culminating in a boring and unfinished looking whole
but noise can definitely be used to achieve something like this:
(open in new tab, its a rad-ass piece of art by Minam Apang)
where the whole is still fairly discernable in person, and at first the accessory bits seem like blotches, but the more you delve in, the more they make sense.
but besides that, noise is sound without an intended frame. can it be pretty? yeah, of course. but is it music? no, unless framed and arranged as such. does that detract from any potential beauty of the noise? hell nope.
