Pop music is still an ass wiggling contest that now wears sensible shoes.
Twenty or thirty or forty years ago, Miley Cyrus would be wearing shoes that would be ridiculous. Think of the glam boots and high heels of yesteryear and how they would have rendered her incapable of gaining the traction she needs to, well, wiggle in front of people.
What did any of it sound like? Who cares?
Nothing changes, ever.
