I mean, if she sung "I like my negro nose with Jackson 5 nostrils", she'd probably rightfully be found dead in her flat.
But seriously, just a redundant question. Her voice neither has the versatility or talent to bounce off so many different directions. If she did have that singing ability, then people would already look at her in a completely different way to now. And anyway, her attempt at singing with depth and meaning = Firework, Roar and Rise.
Maybe a better question is how an album along the lines of Anti would be recieved.
