If you're an actual singer and came up through choir, drama club musicals, or some other level of professionally-trained you likely have been taught that putting your voice into distortion/overdrive is a no-no. There are all types of scary stories about this. To me, this sounds very much like someone not used to and maybe a little scared of screaming and pulling herself back just shy of screech/growl/whatever. Doing it this way, she won't ever have to worry about
developing nodes on her vocal cords, especially trying to grind out one take after another of the live take of a song.
Beyond that, song sounds like someone trying to pull back from a Disney image, or her agent/manager thought it would be a good idea to have this written for her, IDK. Better this than a Playboy shoot I reckon.
Whether she is a manufactured commodity or not, overall the internet sucks and needs to give this person a break. Maybe I'll feel differently when she's selling out arenas or maybe she's already at that level. Who cares.
