I'll never understand the popularity of this song

I really wouldn't want to pay to see her live.

Epic. LMAO

That performance was pretty good and say what you want, but this is a solid performance for a debut artist.
She's improving!!!

She doesn't sound a lot better on the record too, so this is OK compared to that.

OMG lol.

x100000000

What drives "Tik Tok" is the beat that is so catchy, but she has nothing (new!) to offer, her voice is uber-annoying.

I really should've watched it.

I just started to like her.

Horrible.

I love this song. She sings good live and she's cute

Eh, not so good live.
And I don't understand how she's sold more singles in the first week more than any other female.
BUT, she is good, and everyone needs to listen to her album because it has a lot of songs that make this one look horrible.
Oh and enough of the Ke$ha stans, please. >.>

She's so bad live.

after this performance .. NO1 can say that britney gimme more at vma was a bad performance!

kesha is sooooooo bad... her song sucks.. she uses autotune..she can't dance...
i don't think she is funny
and also she is very fat LOL

Math. Christmas iTunes gift cards + winter vacation + party song = #1 smash

Alexz!

Makes sense. But still, this is her first single.. And her ass flopped big time with the whole "Right Round" thing. I just find it peculiar o.O

Well, she was definitely entertaining but not for all the right reasons lmao

I love her though, she'll improve with time

LOL. I want to hear someone really monotone sing this song. Or old and creepy.

"Don't stop. Make it pop."

*looks on YouTube*

Her song has been climbing slow since September, it just didn't hit #1 on the Hot 100 until recently because her airplay was low. It's been top 10 on iTunes though for at least 2 months

lmao. I find it hilarious how a crappy live performance from Ke$ha brought in everyone who's currently viewing the video section. And five guests! :O

Just Dance did the same exact thing last year, and that was her debut. More gift cards were given out this Christmas.
