Katy is McDonald's.
Bey is RED LOBSTER or Gordon Ramsay's at The London, or any five star restaurant.
Gaga is Burger King.
Britney is pizza Hut.
And Ke$ha is Taco Bell.
She's safe, predictable, and her songs can be interchangeable. Katy is forgettable to me because she doesn't do anything that some random girl off the street couldn't do with a few weeks of training.
