Katy Perry has recently gathered her 7th #1 single on the Billboard Hot 100 as a lead artist with Part Of Me in a really short amount of time, which is really impressive no matter how you look at it.

BUT, if you had to choose,

What is the BEST #1 Katy Perry Single

and

What is the WORST #1 Katy Perry Single

Your choices:

1. I Kissed A Girl
2. California Gurls ft. Snoop Dogg
3. Teenage Dream
4. Firework
5. E.T. ft. Kanye West
6. Last Friday Night
7. Part Of Me

Again, the poll will be for the BEST #1 Katy Perry single.

To answer my own question:

BEST: Firework
WORST: Last Friday Night/Part Of Me

Best: TD
Worst: Part of Me

Best: Teenage Dream
Worst: Part Of Me

Best: "Teenage Dream"
Worst: "Firework"

Best - IKAG
Worst - POM

Best: Teenage Dream / Firework
Worst: Part of Me / Last Friday Night

Best: Teenage Dream
Worst: E.T.

Best: E.T.
Worst: Part Of Me

Best: Teenage Dream
Worst: Last Friday Night, it was a good one but like compared to Part of Me it falls very short, it adds nothing it's just a party song

BEST: Teenage Dream
WORST: Part Of Me (for sure)

Best: E.T
Worst: Part of Me

You have issues, it's second best to TD what about it did you not like?

EVERYBODY LOVES TEENAGE DREAM!

Best: Firework
Worst: Part Of Me

Best: ET
Worst: Last Friday Night

I swear it'll end up being a modern pop classic. It's flawless.

Best: Teenage Dream
Worst: Part Of Me

I almost voted for Teenage Dream but I Kissed a Girl is superior
