I don't understand the Britney comparisons even if the inspiration for this cover (Britney's 1999 cover) is nothing but an invitation for that.. if you remember that specific year, Britney was a cultural phenomenon, so big she was highly divisive, everyone, from metal heads to classical musicians and country singers, kids to grandparents, had a strong opinion of her. No one right now can even compare to a fraction of her success back then, not Taylor or Beyonce, definitely not Dua, and certainly not the newer generation, not because they're not capable (Tate is a far superior dancer than Britney Spears ever was, Addison can't sing nor dance or even tone up but I'd argue she's prettier and has what Britney never had: participation in her own image)... but simply because we live in a time of short-attention span and being able to voice out our opinions and overly-scrutinise makes all objects less intriguing.
There's clearly a thirst for that level of mega stardom but at the same time, the current culture of quickly deflating the fantasy surrounding that makes it impossible to happen. I will say that all these pop singers who make super repetitive songs are at a good point of their careers where they can do exactly what Britney Spears did when she released Toxic and defied her own sound, and secure longevity.
