BTW anyone knows where I can download the MP3 files for the performances of the X Factor. Since I don't live in the UK anymore... I can't buy them on iTunes
I bet Katy performs Teenage Dream, like Usher performed DJ Got Us Falling In Love. I don't know why people come on and sing songs that are on their way out when it's a perfect platform to get publicity for the next song. Usher could've worked Hot Tottie into his medley and got that some sales.
