美国派7:索爱天书 插曲

歌手：katy perry
　　歌名：hot n cold
　　You change your mind
　　Like a girl changes clothes
　　Yeah you, PMS
　　Like a bitch
　　I would know

　　And you over think
　　Always speak
　　Crypticly

　　I should know
　　That you're no good for me

　　[CHORUS]
　　Cause you're hot then you're cold
　　You're yes then you're no
　　You're in then you're out
　　You're up then you're down
　　You're wrong when it's right
　　It's black and it's white
　　We fight, we break up
　　We kiss, we make up
　　(you) You don't really want to stay, no
　　(but you) But you don't really want to go-o
　　You're hot then you're cold
　　You're yes then you're no
　　You're in and you're out
　　You're up and you're down

　　We used to be
　　Just like twins
　　So in sync
　　The same energy
