It's cookie cutter.
But then, so is every single commercial genre. Everybody is looking for the big hit, and the easiest way to find it is to copy something else that has already been a big hit.

And copy.
And copy.
And copy.
Until there is a new artist that somehow breaks through the clutter with a new sound that hits it big.
And then they start copying that sound.
And copy.
And copy...
