... seem to be the only thing consumers are spending money on anymore. If I let anyone above the age of 30 hear that song, they'd spontaneously combust into an endless rant about how "back in their day" hip-hop was more than just hard beats and gibberish lyrics. Oh yeah? Are you referring to Sir Mix-A-Lot's timeless classic "Baby Got Back"? Probably not, because people were lodging the exact same complaints against that song "back in your day." That songs is three verses about ass, and it won a Grammy. Things weren't even sort of better in your day.
Or what about Juvenile's "Back That Ass Up"? Cry all you want about Cash Money Records making Young Thug into a nearly-impossible-to-understand star, but if the masses didn't embrace Juvenile rapping about asses so enthusiastically back in 1999 ...
... none of that would even be happening right now. That's not to say Juvenile is a bad rapper; in fact, he was one of the best from the South in the '90s. The point is that rap has grown so much from its early beginnings that it's no longer just two categories -- gangsta rap and more gangsta rap.
