Reducing Beyonce's choreography to "hairography and booty shaking" proves that you have never actually seen a video of her dancing.
Note: She is pregnant in that 2nd gif. The other girls could never.
Beyonce is cut from the same cloth as older performers where musicality and big performances went hand in hand with dancing. Michael Jackson, Tina Turner and even Prince.
Dancing is a part of performance. It's not mandatory, but it's commonly used in pop music to create visual interest. It's an
option, one a lot of these girls take, and some are better at than others. As a listener of pop music, I just don't bother with girls who don't even try. I have higher standards for artists I listen to (and invest in) than chart candy.
