No.

Explain Tik Tok 2.0, California Gurls, and the sing-talk Peacock

Are you serious?

Exact-replica melodies don't lie

Yes sure, Ke$ha inspired that.

(And btw, she didn't inspirate CG, she's not even an inspiration, blame Dr. Luke ).

Avril i think. Then Ke$ha tbh.

Avril and it's not even close. I know most people that post here aren't even old enough to remember a decade back, but she was the posterchild of the OMG****INGHUGEANDSUCCESSFUL pop/rock girl "backlash against bubblegum Britney & boybands" movement.

But it's not an entirely fair question either because of how much longer she's been around.

It's not a matter of inspiration, but influence.

Um.... I should blame a producer for her song? Oh. Good cover, tho.

Katy Perry used Dr. Luke first, in 2008, before K$, he produced Tik Tok and California Gurls, but Katy wasn't inspired by her.
