I don't know what is it, but Katy is not doing it for me at all this era. I don't like any of the songs she's lifted so far, instead I enjoy looking at her promotional photos. Is she working with different producers and song writers now??? Cos they really suck!!!! I am not sure if i'll be buying 'Teenage Dream' or not, but that's not a biggie because she's got larger and presumably NEW fan base which certainly will...
