In all the time of me hearing about her, I feel she has yet to build a fanbase, nicki had real barbs and fans on deck with beam me up Scotty, then she killed feature after feature before dropping....Ab hasn't done this IMO. also, as a female rapper nowadays, you HAVE to have female fans, I really think she's turned women off with the constant hate, any time you see a blog covering her, she's beefing. Missy was the last female rapper to appeal to both sexes, and that cuz her music was just dope, very gender neutral
And a Rick Ross ERA? nicki ERA? I think you're way overstating their influence, theyre popular artists at the same time, in addition to others, but neither have/had their own era, especially not nicki. When I think era, I think no limit/master p, death row, cash money (the original), bad boy, ruff ryders/DMX, jay z/roc a fella/state prop....none of the artists you named have accomplished that
