The thing about music is that it is an art (duh). One that all human cultures seem compelled to create. Give people plastic buckets and a bit of time and likely as not they will come up with something aurally interesting. Whether that tickles my fancy, doesn’t make the sound good or bad. Give artists ”rules” they have to follow and eventually, some creative person will find a way to break those rules in interesting and compelling ways, even though, by the “rules”, the music is bad. For visual reference the impressionists, cubists, Duchamp, etc.
And yes there will always be a ton of “bad” music relative to the music I enjoy, but if I am honest with myself, even most of the music I don’t like, isn’t bad objectively*. It’s just that I don’t enjoy it. Which is fine. What bothers me on this thread is the dismissal of entire genres of music as bad without explicitly showing what the evaluators are and showing that those evaluators are somehow inherently true. It bothers me, because it often seems like a way of simply reinforcing one’s own biases by dismissing traditions that don’t fit the form. In other words, many of the accusations of being bad are directed against Rap, Hip hop, and its descendants (trance, much EDM, most of Pop these days etc.), music associated with marginalized groups.
I don’t like much Rap. It probably makes up less than 1% of my library. But I do recognize there is a ton of good rap out there, it just isn’t my thing, and the history of it (like the history of Jazz) is fascinating. But if we are hoping to talk about good music on a science site, it might be interesting to try and come up with some definition of good and bad that don’t simply reflect the biases of one particular cultural tradition. Is it possible to make up rules that would apply equally to human non-language sound generation from all traditions. Anything else is just ”old person yells at clouds”, which is fun to do, less fun to listen to.
*I don’t have any idea how to define bad music, objectively.
