This is a paradox, though. You’re saying that one of the most popular types of music “lacks musicality”. The only way that can be true is if you start with a narrow and arbitrary definition of what “musicality” is.
If you examine the history of ideas of what is “real” or “authentic” or “objectively good” in music, who has been a proponent of those ideas through history, and why, you will find is that a lot of it is rooted in white supremacy. The idea is that a certain style of white European music is the only true music, and that other music is only valuable to the extent that it happens to fit within the theoretical frameworks developed around those styles.
I guess what I’m saying is, please watch this excellent video, “Music Theory is Racist” by Adam Neely: https://youtu.be/Kr3quGh7pJA
I think saying western Top40 lacks musicality within the context of western music is a totally fine thing to do though, because it's not that it's something different and good. It's trying to be western music, but it's derivative and shallow interpretations of it. Western music being a broad brush, including many of the subcultures of music contained within somewhere like America.
Top40 is often the crap versions of the good stuff that's out there, cheap versions of the culture that dwells beneath. My main point is that it's popularity is not because of musical excellence regardless of what that excellence is for the given genre/culture, it's manufactured popularity through repetition and distribution. Sometimes they pick good songs to pedal, so I'm not saying Top40 contains zero good music. It's just not a good representation of the state of music culture by any means.
It's hard to talk about music without seeing it through your own experience, because it is a language you share with those who know it. Adam Neely about his Jazz Ambassador tour, said he felt he could connect only tangentially with the Mongolian performers. There was some crossover and they could speak some of the same musical terms, but there was much of their musical language that wasn't immediately compatible. Sort of like a French language speaker sometimes interjecting English words, you can hear them but you can't intuitively know the context, and unless you knew both you couldn't really comment on how well the sentence was executed. But of the genres that end up in Top40, I typically know good music in those genres, so I feel I am able to comment on their quality.
Ok, why don’t you prove it by writing a hit pop song? Come back to this thread when you have your gold record, I’ll wait
