TSwift's writing is personal and emotional for the GP, even though she has millions of writers "LIKE, THE NEW ROMANTICE, BBE! WE'LL GO DOWN IN NEW YEARS EVEEE-uhh" or whatever the songs are now.
She just has the JLaw way of being relatable, in a John Mayor's poetry/guitar girl type of swing. People eat it up like coffee.
Katy is like a Britney.. big boobs = less respect, especially when you sing about 'CALI BOOBIES~ OH WHIPPED CREAM.' She'll deffo be remembered though.. she's had gr8 marketing. People get MAD about this

Her career has been too successful to be "ahh, another chip on the road! recycle her." type of starlet.
She has a good voice in her songs, its perf for all genders.. it's bland but special, girly but boyish, quirky but shallow, interesting but dumb. The songs, themes, and production isn't just Jessie J vomit-alphabet, it's the type of pop that gets a crowd of wild hearts thumping and faces glittering,
