Im Shocked but I actually really liked it Buuu to me, the begining isnt that good and her histeric screams arent good neither, but the chorus is really dramatic and I like it.
Although she didnt inovate a thing from my prespective, this actually reminds me of Poker Face, but Im glad it's not an exactly copy coz I hate Poker Face.
I Gotta Feeling that this song is gonna be a smash hit!
