De gustibus non est disputandem. (my latin's rusty, so i probably spelled that wrong...)
all "art" is subject to taste. what one person (or one billion people) finds to be good, another person (or another billion) might despise and find to be infantile scribbling. case in point: i feel that Picasso, widely cited as one of the greatest artists to ever live, is overrated at best, and a scrawler at worst. but that's my opinion.
to bring it back to music: some people like noisecore, and find beauty in it. most people find it abrasive, unenjoyable, and even offensive.
perfect case in point. this is one of my absolute favorite bands, and this particular song is pretty much a giant "fuck you" to the mainstream music industry. literally, they're asking "don't you think we could make a multi-platinum album and rake in the money (italics paraphrased and condensed from all verses)? we could, but... (noise)". the thing is, this band is capable of making very beautiful music. but even then it's not to everyone's taste.
and because i feel like sharing, my favorite Neubauten song:
even that song, which i find to be incredibly beautiful, nuanced, and poetic, most people would hear as abrasive noise.
