Okay, so this girls name on Youtube is Out of Lines. She's such a good singer and made a song for Throne of Glass and aghhhh. It may not sound like TOG at first but wait till the second verse. Here are the lyrics

(1ST VERSE)
A little girl,
A little city.
Crushed her dreams and told the world:
That nothing was fair
Not at all.

She stole his money,
and left the city.
Carried the few things she owned.
A little girl,
Not here anymore.

(PRE-CHORUS)
She'll build a thicker skin,
No one could tear her down.
It was a natural disaster,
That wasn't natural at all.

She wants the glory and,
the fame that comes with it.
She's not a psycho,
She's not malicious,
She's not a tyrant,
She's just ambitious.

(CHORUS)
She holds the kingdom in her hands,
But it's not hers,
But it's not hers yet.

She wants it from a man who can't understand,
The way it works,
How the game works.

Hold onto the crown on your head,
Or kneel to her who took the throne.
She took a breath; took off the cloak,
Took a breath and threw a stone.

Hold onto the crown on your head.
Don't shut your eyes and don't look tired.
She came with nothing left to lose
And so she'll leave with the empire.

(2ND VERSE)
A little girl,
Who's not so little.
Rose to fame by getting rid of,
Peoples problems but she still has her own.

A war like this could end in pieces,
Are you prepared to risk it all?
And ask yourself how far you'll go to save your home.

(PRE-CHORUS)
It's in her blood to rule,
Her highness has been found.
She is the heir of ash and fire,
And she will burn you to the ground.

They stole what could've been,
And turned the greens to browns.
She's not a psycho,
She's not the villian.
She wants the magic,
The world is missing.

(CHORUS^^)
