AMAZING! Love the song and it's sooo diferent! Love It

It's really really GOOD.

Will Capitol rush release this to iTunes now?

I won't make the same mistake as with PoM listening to the leak a gazillion times only for the song to be burnt out when the music video is released. Listened to the leak twice and now I'm closing the link.

This is Katy's best lead single.

It's underwhelming but it'll probably grow on me.

I hear fun. all over this track. Did Nate Ruess have a hand in producing this song?

IF they do, it will mess up her first week sales...

I love Katy, but I feel underwhelmed by the song.
Maybe my expectations were way too high.

Anyway, I will still buy the song on iTunes. Hopefully it grows on me and goes #1.

Love it.

NO ****ING BRIDGE THOUGH

AMAZING

Sounds like something a 13 year old would make which is ironic considering the image change

NO. They won't do that.

EPIC EIPC

Pretty good

Capitol is losing its touch I see.

I'm so proud of this track, it's definitely her best lead single in my opinion. My only complaint is the lack of a proper bridge but the whole production is huge and that final chorus gives me life.

This is so disappointing, Katy can do so much better

So uneventful and uninspired.
