It isn't "leaking", as I said on the other thread, the label is giving out album tracks to different presses on purpose to supposedly promote the album and create buzz.
That's Jesy on the first verse right? She sounds different but in a good way.
At first I thought it was Jesy switching with Jade, but everyone's saying it's all Queen Jesy.
While I love all of it, T-Boz's parts are actually my favorite. I had forgotten how much I love her voice and am surprised how well it blends with Little Mix.
I'm kind of shocked how little Perrie is on this song. I do love Jesy and Leigh-Anne taking the biggest parts though.
Now all the girls have gotten their turn. 
The 90's Spanish guitar in the intro.
