She needs to perform BTGOG at the GRAMMYs so I can finally feel like stanning for ha is respectable.
About her head voice, she did the same with Unconditionally. I love how she saves the belts for the last chorus now. And of course she is still learning how to use her voice. Until one gets to Bey's level, you never stop. Most people neber reach her level ofc. She can work on her lower register now.

the verses in Firework are still mediocre.
