Hip-hop & Rap in general is basically emphasizing on the same subject; i.e. money, cars, bling, bitches, hoes, pimps, players, hustlers, dope, weed, fame, glamour, & other crappy trends!!! ...and poor production, & mostly club catered hits!!...
That's why rap records aren't selling!!!
...cuz people are already tired of hearing the same ol' shit every day!!!
...& no wonder many people don't listen to rap or hip-hop or they just listen to conscious or underground hip-hop just cuz they're stickin wit the original roots as art!!!
Either they need to come up more creatively & expand their knowledge a lil more, or just continue to rap & produce the same shit everyday so they can keep flopping & flopping.......................................................................
