Artist: Esthero
Song: "Never Gonna Let You"
Scene: Opening montage
Lyrics:
‘cause I don’t wanna let you go, I don’t wanna let you go.
I don’t wanna let you go, I don’t wanna let you go.
Is there a problem, did I hear you right?
You say your handcuffs are a little tight,
What’s wrong now? You used to love this game.

Lyrics:
Dig up her bones, but leave her soul alone
Boy with a broken soul
heart with a gaping hole
Dark twisted fantasy turned to reality
Kissing death and losing my breath.

Artist: Serena Ryder
Song: "What I Wouldn't Do"
Scene: Closing sequence.
Lyrics:
If you should fall to pieces
You know I’ll pick them up
There are so many reasons
I’m never going to get enough
If you should leave this country
You know I’ll come to you
Because you always love me
oh what I wouldn’t do
oh what I wouldn’t do.
