My two
cents: Just because the pop scene is volatile does not mean it is all random. I think this is what Peru is failing to fully articulate with his questioning. A whole industry is trying to capture a magic, but that magic is always changing, so standard formulas only get so far. The big hits tend to perfectly combine what is familiar/comfortable and the bleeding edge of the most impactful new trends in sound, fashion, and statement. That doesn't mean "most innovative," it means most impactful. In this, pop is an art pushing culture, not the limits of concepts, which is often too experimental and uncomfortable for many, but it also can't rely too heavily on established notions of what "quality" means or it's boring.
For those that find the balance between these, usually professional artists (whether celebrity or not) whose whole personal world
is the scene, and the effect of their attunement with what the scene is becoming in addition to their capacity for raw human expression through it seems to make something timeless. I do realize there is still luck involved, so I don't think that everyone who makes something that
could be an international hit will get it heard, but the mega hits have definitely tapped into a resonance with the mind and heart of society on a level that cannot be mechanically manufactured.
I mean, indie artists do the same thing, just within a niche rather than the largest span of culture. For example, we have a lot of Neon Bunny fans in here. Why is she so good? If you try to break it down in analysis, her works aren't super challenging, sounds not too innovative. But if you know her scene of fuzzy electrosynth, you know she is bringing a clarity of melody and distinctiveness of emotional message that was lacking in the rather amorphous genre, and now she's even bringing in touches from R&B. But only those into the genre would go "this is something really special" because they have the focused context of the smaller scene in mind.
Pop is when the context is the entire flow of music and its role in larger society. Musically you have wide-spectrum flows and shifts of influence like country, jazz, rock, hip-hop, electronic. Thematically you have hot topics that press on what people are dealing with socially, but then more basic/shallow aspects of simply being human. Where familiar hits newness makes impact, and this is in the established music smashing into innovations, in genres smashing into each other, in familiar feelings and mindsets smashing into new experiences and interactions with new ideas and kinds of people, or even familiar yet deeply personal sorts of feelings hitting the open air for once (to the average listener, not necessarily the first time historically).
So anyways yeah, it may often come off "dumb" in terms of refined artistic creation, but if you ever make refined artistic creations you'll find that a rather specific context is required to really appreciate them (and that can go not just for perspective or music style, but your present mood, as sometimes you just want to party and not be focused on specific things). Pop megahits can be appreciated by people who just live here in our world, tho sometimes a bit more focused to being appreciated by the people who live in the country it was written in. Accomplishing that without being boring is very difficult to do, if it is a work project to you, but may come as naturally as breathing if you're wrapped up in the scene and what it's becoming.
And while it may change constantly, and not hold the deepest and most articulate statements, that doesn't mean that it's all superficial and meaningless to our world or anything really important, but then that is a whole different topic I don't have time to write on in full because I'm heading out soon. I'll simply say that some discussions are still far and wide, socially hindered, just like some (many) parts of the world still lack clean water. Pop is doing it's work on culture, not on philosophers. Yet some things also bear repeating as they are new to us each day in a sense, and many people are born each day to go through the common human experience.
