Those BELTS slay her entire discography I must say. Those are some clear belts, she can actually sing in her upper register and hold it. I love the rasp in her voice too.
The guy who did this has STEMS of the majority of songs he used..
He has actual studio vocals, background vocals, dry vocals, lead vocals everything. So this recording isn't live but he added a reverb and EQ effect to make it live. The vocals are all real, she recorded all of them in the studio.
I honestly understand why they cut the album version the way they did for POP but those vocals could really made the song stand out more.
