Katy Perry had great success with Hot and Cold.  After
her debut single, I Kissed a Girl, Hot and Cold also shot
up the charts.

The song is great to practice listening in English.  It
shows the way English speakers reduce AND to "N".  

I have a dog and a cat.        (normal speed)
I have a dog n a cat.            (fast speed)

Listen to the chorus as Katy Perry sings Hot and Cold.  
Notice how the AND becomes only an N.

Below the video there are lyrics with a listening
exercise.  Listen and fill in the blanks.

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

And you
Over-think
Always 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 and you're out
You're up and 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-oh

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
So in sync
The same energy
Now's a dead battery

Used to about nothing
Now your plain
Boring

I should know
you're not gonna change

Cause 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

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 (woah)
You!
But you don't really want to go-oh (ohhh)

You're hot then you're cold
You're yes then you're no (no!)
You're in and you're out
You're up and you're down (you're down!)

Someone call the
Got a case of a love bi-polar
Stuck on a roller coaster
Can't get it 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 and you're out
You're up and you're down

You're wrong when it's right (When it's right)
It's black and it's white
We fight, we break up
We kiss, we make up (We make up)

You're hot then you're cold

(Ohhhhhhhhhhhh)
You're yes then you're no
You're in and you're out (Oh!)
You're up and you're down
(Ohhhhhhhhhhhhh)

You're wrong when it's right
It's black and it's white (Oh!)
We fight, we break up
We kiss, we make up

You!\
You don't really want to stay, no (woah) You!
But you don't really want to go-oh (ohhh)

You're hot then you're cold (Cold)
You're yes then you're no (No)
You're in and you're out
You're up and you're down (Dooooown)
