"Cold, Cold Heart" by Hank Williams

I try so hard, my dear, to show that you're my every dream
Yet you're afraid each thing I do is just some evil scheme
A memory from your lonesome past keeps us so far apart
Why can't I free your doubtful mind and melt your cold, cold heart?

Another love before my time made your heart sad and blue
And so my heart is paying now for things I didn't do
In anger unkind words are said that make the teardrops start
Why can't I free your doubtful mind and melt your cold, cold heart?

You'll never know how much it hurts to see you sit and cry
You know you need and want my love, yet you're afraid to try
Why do you run and hide from life, to try it just ain't smart
Why can't I free your doubtful mind and melt your cold, cold heart?

There was a time when I believed that you belonged to me
But now I know your heart is shackled to a memory
The more I learn to care for you, the more we drift apart
Why can't I free your doubtful mind and melt your cold, cold heart?

"Hot N Cold" by Katy Perry

I just heard this on the radio this afternoon (I think I know who she's talking about):

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

And you always think
Always speak
Crypticly

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-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
Now's a dead battery
Used to laugh 'bout nothing
Now your 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 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-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

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 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'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-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
