If Pour it Up (Single) and video were released at around the same time, it could have easily went Top #10.
What Now, just happened. Right Now, left in the dust. Diamonds was preformed a lot. Stay was preformed, a little more would have helped it get that #1. Jump could have been a thing: good sampling always helps both versions of the song.
Talk That Talk (Single) could have smashed. So many missed opportunities.
She did handle Loud well, I must say.
However, what would happen if she invests in her eras?
