I agree with sundee! i was like isnt this the intro of another song? i mean if u suddenly hear it on a radio u will surely think of that song! but then it isn't. is it really no other intro this big2 people can produce?: the verse is ok, but the chorus..omg..almost the same with california girls..and it hurts my heart thinking why it sounded the same..at least put a lil twist in it.. i thought TD is the part 2 of CG! lol. no offense. i like Thinking of you for slower KP, and hot & cold for catchy KP. those work the best.

just work on the chorus part all over again then it'll be okay.
