I am sure someone can figure out which song it is. While the music sounds great and sells, my theory is that it comes as a result of losing music classes in many public schools. Over decades it has led to a loss of complexity.
Then again, I am probably just old.
It wouldn't be terribly surprising if it's the audience that has dragged things towards simplicity.
Could also be the homogenizing effect of recommendation algorithms that select for mass appeal, a song that everyone likes at an average of 7/10 is selected for way harder than a song that 50% of people like at an average of 9/10.
But violins are just an instrument, no more sophisticated or less than any other arrangement choice. Now the complexity is in the rhythmic interactions, and the timbral palette available to producers. The musicality of pop musicians and especially studio performers and producers is just unreal right now.
Other than that some of my favorites from the last approximate decade in no particular order (in format: album - artist) are froot - marina and the diamonds; I feel alive - TOPS; shabrang - sevdaliza; unfortunately, terror jr - terror jr; take me apart - kelela; somewhere in between - verite; dogviolet - laurel; empathogen - willow; expectations - hayley kiyoko; once twice melody - beach house; the fool - ryn weaver.
Pop is hard to define as a genre, particularly it tends to blend into r&b and indie rock so some people might categorize some these differently. And most are "indie pop" but afaict that's just pop by non-famous musicians. That ryn weaver album is probably the best in the list, it's a monster masterpiece that deserves to be more widely known.
But I still miss some of the subtle harmonics from edits like this https://www.youtube.com/watch?v=eVhl896h2NI . There are other studio sessions with isolated vocals which afaik are not made this way anymore
ps: ryn makes good pop, colorful, but i don't know, maybe a different approach to voicings, it's missing something

If you like knower and thundercat there is a ton of great music that in that intersection of funk, pop, contemporary jazz. I was trying to stick to more "straight pop." Anyway with those guys I don't think the musicianship or sophistication is remotely in dispute.
There is a great podcast called Switched on Pop, which delves into music theory behind pop hits and their songwriting and arrangements, and analyzes them to show what makes them great. It will give you fresh perspective on how much thought and talent goes into some of these songs. https://switchedonpop.com/
