I find the majority of modern pop is formulaic, which is fine, no change there from any era of pop.
My personal issue is that the formula is not to my taste - anonymous girl singers in the main, making too many breath noises, singing down their noses, and the track is over-produced to within an inch of its life.
It feels like music made by a computer programme, which takes the basic ingredients and re-hashes them changing things very slightly, but basically making everything sound seriously similar.
I feel the absence of musicians who write their songs, craft them and hone them, record them, and take them out on the road to play live.
Now we have anonymous teams of producers churning out machine-produced music with utterly anonymous vocalists on top, there is no soul, no passion, and no feeling in any of it.
Until recently, you could identify a pop star by their look and sound, now any one of them could be any other one.
It only bothers me when I DJ and play that type of music, but the people it is aimed at sit on their phones and ignore me. It;s when I play the classics from the 60's to the 80's that people actually get up and dance.
There is a message there I am sure.
