Yeah they are. Especially Teenage Dream, Firework, E.T and Wide Awake. But usually she nails them.

Not really. I can't only sing 'Firework' from her.

Your fave couldn't and she's supposed to be "the vocalist of this generation"

Nah. "Firework" is kinda difficult though.

oop

I don't think they're that hard to sing. Pearl is difficult imo but all the singles are easy.

Umm. What?

In general I'd say yes they are easy to sing.

Yep. I mean not all of them, but definitely some.

Nope. Firework is probably the hardest, and it's not that difficult. Kelly Clarkson having a supposedly difficult time with it is probably more about adjusting the song to to fit the optimal range of her voice.
