Even though I HATE THE SONG, ( sounds like she withheld this song from Destiny's Child ) . Beyonce is right., girls do run the world (when it comes 2 music) She is a great vocalist & overall performer. the former she is marketing 4 on. Rihanna? can hook us like no other, whether u like it or not her songs suck U N & yall still singing em. Katy Perry ? Yeah we love her false innocence, & bubble gum fluff . Brittney? We love that she still works hard after a post partum nervous break down. GO BRIT-BRIT. Adele? Don't know much about her, never heard of her till now. I keep hearing the same song ova on the radio, so based on how many times I have heard that one song, she deserves 2 B #1. Then there is Lady Ga-Ga? Yes she can sing. I actually like a small few of her songs, but come on folks let's be real. U don't tune into Ga-Ga 4 her music. Yall luv her theatrics. Which by the way R REPULSIVE. But giving credit where it is due, all of these ladies rule the world N there own right , with their STAR POWER ! THEY RUN THIS MUTHA!
