They sound better combined than either of them do on their own . still crappy as hell

If it's any consolation, i'll stick with Van Halen's “California Girls”, thank you.

It was obvious from the start that KP's song was derivative. I'm so over her. Can we just get a sex tape and move on?

I bet it took longer to mix them together than it did to make the originals…
And yet, to the producer's credit, anytime I hear either one it sticks in my head like glue for days.

Well, they're both produced by the exact same guy: Dr. Luke—and most of his stuff is super-catchy. And sounds totally alike. If anything, both of these songs rip the same riff off Kylie's “Love At First Sight.” But who can keep track!

if you actually listen closely, their chord progressions are actually different. they just sound similar because of the beat and some of the sounds. but then again, there has been plenty of these case in which different songs sound similar. its just that there is a limited amount of chord progressions people can make until it goes back around to the same one. just like how we are in the 2010's and fashion is back at the 80's

Wait, you mean one tedious club hit sounds similar to another tedious club hit? I am SHOCKED.

SOOO. MUCH. AUTOTUNE!!!  GAAAAAAAH!!!!

The irony is that Katy Perry was the one who gave Kesha her start. Kesha sang backup on Katy's song “Right Around” with Flo Rida. Music execs were impressed with Kesha and offered her a record deal.  Now here we are and people think Katy is copying Kesha, lol. I agree with previous posters that this is the fault of the producers who worked on both these songs.

OMFG I WNATED TO PUT THAT ON HEREE!! but then i wa sliek Nahhhh!! Lol FML HeHe

Listen to pop music much? Many songs have similar BPM's and can easily be overlapped/remixed, and are often utilized in such a manner when a DJ is playing them. Not really a surprise.

This is not surprising. Both songs are trash.

They're from the same producer. Read it in Entertainment Weekly.

Britney Spears - Piece of me. Same song as those two.

my braaiiiin!

I've been thinking the same since the first time I heard “California Gurls.”

my favorite part is “crunk… junk…. DRUNK”
