Well barring Lana and Ellie because I don't know how they're considered new girls
Tinashe is the most talented on that list, in my humble little opinion. Girl can sing, dance, and write a really cute song. I already borderline stan for Iggy, and out of that list I voted for Mų and BANKS. Admittedly I'm not granular with everyone on the list, but yah.
Also: SZA needs to be on that list. Her and Tinashe are the best things in R&B right now.. AlunaGeorge too
