Candice and Kree are at the top of the heap.
Amber, then Angie round out the middle.
Janelle and Lazaro are in the bottom as far as talent goes. (Although Janelle is a few steps above Lazaro.)
Unfortunately Amber and Angie are the only two that are marketable.
Kree is the least marketable. She's vocally talented. But, the country market is more about looks than talent. It's even shallower than pop and tejano.
