Little Do You Know by Alex & Sierra

Lyrics:
Little do you know
How I’m breaking while you fall asleep
Little do you know
I’m still haunted by the memories
Little do you know
I’m trying to pick myself up piece by piece
Little do you know
I need a little more time
Underneath it all I’m held captive by the hole inside
I’ve been holding back
For the fear that you might change your mind
I’m ready to forgive you, but forgetting is a harder fight
Little do you know
I need a little more time

I’ll wait, I’ll wait
I love you like you’ve never felt the pain, I’ll wait
I promise, you don’t have to be afraid, I’ll wait
Love is here, and here to stay
So lay your head on me
Little do you know
I know you’re hurt while I’m sound asleep
Little do you know
All my mistakes are slowly drowning me
Little do you know
I’m trying to make it better piece by piece
Little do you know
I, I love you ’til the sun dies

I’ll wait, just wait
I love you like I’ve never felt the pain, just wait
I love you like I’ve never been afraid, just wait
Our love is here, and here to stay
So lay your head on me

I’ll wait (I’ll wait), I’ll wait (I’ll wait)
I love you like you’ve never felt the pain, I’ll wait (I’ll wait)
I promise you don’t have to be afraid, I’ll wait
Love is here, and here to stay
So lay your head on me
Lay your head on me
So lay your head on me
‘Cause little do you know
I love you ’til the sun dies

Summary:
Castiel is one of the world’s biggest rock stars. Lead singer of The Garrison. He’s living a life of decadence, but he can’t come up with inspiration for their next album, and they’re supposed to be back in the studio in a matter of weeks. It’s no secret that The Garrison’s music is mostly about Castiel’s sex life, and the man experiments in lovemaking as often as he does with the band’s sound. Now, Cas needs a new sexual experience to inspire his music.

Dean Winchester is a Mixed Martial Artist with a reputation for being able to take a hard hit and being able to deliver an even harder one. Having a fight in Vegas is surreal for the Kansas native. Being propositioned by a rock star after the fight is equally surreal. First of all, Castiel is decidedly male with a reputation with the ladies as sordid as Dean’s own. Second, his proposition to be at Dean’s mercy in the bedroom is as ridiculous as it is intriguing.

Lyrics:
Love took me by the hand
Love took me by surprise
Love led me to you
And love opened up my eyes

And I was drifting away
Like a drop in the ocean
And now I realize that 
Nothing has been as beautiful
As when I saw heaven’s skies
In your eyes
In your eyes

And every time I drift away
I lose myself in you
And now I see I can be me
In everything I do

‘Cause I was feeling as small
As a drop in the ocean
And now I realize that
Nothing has been as beautiful
As when I saw heaven’s skies
In your eyes
In your eyes

Love took me by the hand
Love took me by surprise

And I was drifting away 
Like a drop in the ocean
And now I’ve realized that
Nothing has been as beautiful
As when I saw heaven’s skies
In your eyes
In your eyes

Summary:
When Dean and Castiel are tricked to go on a date, neither is happy about this. To get back at their deceitful friends, they hatch the perfect plan: pretend to be dating, and gross out their friends with their over-the-top, disgustingly cute romantic relationship – and then break up in the most despicable manner imaginable. As it turns out, you can learn a lot from someone just by pretending affection.

I Was a Fool by Tegan and Sara

Lyrics:
Do you remember I searched you out
How I climbed your city’s walls?
Do you remember me as devout
How I prayed for your calls?

I stood still is what I did
Love like ours is never fixed
I stuck around
I did behave
I saved you every time
I was a fool for love
I was a fool for love
I was a fool [x2]

Then you blamed me and blocked me out
How long did you think I’d last?
Then you disappeared for weeks to pout
How many times could I pack?

But stand still is all I did
Love like ours is never fixed
Still I stuck around
I did behave
I saved you every time
I was a fool for love
I was a fool for love
I was a fool [x2]

If you’re worried that I might’ve changed
Left behind all of my foolish ways
You best be looking for somebody else
Without a foolish heart, a foolish heart

But stand still is all we did
Love like ours is never fixed

I stuck around
I did behave
I saved you every time
I was a fool for love
I was a fool for love
I was a fool [x5]
