She was cute. Khalid's vocals were a little too shaky for me. I hope this isn't his standard...

Obviously, the girl can move, so I predict a combo of backtrack, pre-recorded vocals and live vocals thrown in between so that we can see her dance and perform her ass off.

Ideally, she will be mostly all live vocals. I think she is coming a long way, and she already sounds better on her own than with that grou.
