Every pop music genre has a signature sound. This is acoustic branding. It's vital for pop-music to function that the audience can determine in a fraction of a second what brand is being offered. Nothing deep going on.

   I hear it as an incredibly dynamic 
   and forward-looking genre.

What dynamic and forward-looking about 3 decades of "where da hoes at where da bitches at"?
