It's not a matter of vice or filth or objectification of women.
It's a matter of boredom.
Fifteen years of the same themes and the same scenes of be-chromed cars, wads of 100 dollar bills, and gyrating women in wardrobes of g-strings and hot pants. Even the wardrobes have been mostly untouched by the decades of fashion changes.
Perhaps it's that the rap stars of today have the same dreams of wealth and success of the stars in rap's fledgling days.
Or perhaps it's just that a small circle of rap video directors have a monopoly on the industry.
Thank you, Fear of a Black Hat for enlightening me.
