After avoiding it for quite long time, I finally listened to "Just Dance" and watched its video and I really feel sorry for the people who say Lady Gaga is better than Christina. Come on, if her "biggest" (less floppy) track sounds like that, you don't deserve to be compared with such a good singer.
Now, about the clothes, was it gaga who invented leather clothes/ superhero look/ mask?
I mean...
Hasn't it been done before? *cough* Annie Lennox*cough*
If I had to copy one of the 2, I'd much rather copy Lennox.
So just stop it with that ugly comparison with Gaga. I'm sure Christina must be too busy taking care of her child (which leads to...

no, I won't go there) to copy a nobody.
