Hot N Cold by Katy Perry.

You change your mind
Like a girl changes clothes
Yeah you PMS
Like a bitch, I would know

And you overthink
Always speak cryptically
I should know
That you're no good for me

'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
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 then you're out
You're up then you're down

We used to be
Just like twins, so in sync
The same energy
Now's a dead battery

Used to laugh 'bout nothing
Now you're plain boring
I should know that you're not gonna change

'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
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 then you're out
You're up then you're down

Someone call the doctor
Got a case of a love bi-polar
Stuck on a roller coaster
Can't get off this ride

You change your mind
Like a girl changes clothes

'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

'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
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 then you're out
You're up then you're down
