It's the same.Your fave and others did it to get better chart position just like Katy's doing it.
Your fave did remix on her 2nd single and called not 1 but 2 hot female artists for it.And you're acting here,sit the **** down.
I know what Britney did sweetheart. We all know what Rihanna and Britney did. But inevitably Katy is worse because she is persistently trying. So YOU can sit down and accept this embarrassment.
I have a lot of respect for Katy doing this remix. She knows she'll get a lot of hate for doing it, but she's courageous and doing one anyway. She doesn't care about what the public think. Good for her. A shining example to us all.
