Not really. She's rated fairly. Let's judge Prism.
Roar - cliche, childish, and no evolution from her last album
Unconditionally - very clunky chorus, melodically and lyrically
Dark Horse - "levitate, like a bird without a cage" is just one of the many cringeworthy lyrics
This is how we do -
International Smile/This Moment/Love Me - All very cliche
Etc etc etc. Katy has good moments like Spiritual or TOTGA, but overall she's a weak writer.
Having listened to ALL of Taylors, Gaga's, and Katy's discography, I'm gonna say Gaga at her best. At their worst they ALL have terribly cringy lyrics especially Gaga, though I know she knows they are cheeky and not serious.
