This is my take on Viva la Vida if it was from Luna's perspective.

lyrics:
I used to rule the world
The moon would rise when I gave the word
Now every night I sleep alone
On a world so far from home.

I used to walk in dreams at night
Banish fear from equestrian eyes
Listen as the crowd would sing
“Queen of the sun,
Praise be to thee”

One minute I had it all
Next the moon began to fall
As I succumbed to jealousy
Bring forth the night, I will be seen

Down on Equestria lights are burning
Even without me the world keeps turning
If I could go back, I’d change my words
But time only ever keeps marching forward
For my crimes and my selfish ways
I’ll be stuck here forever
There’s not a day on the moon
That I’m not longing for you

It was my jealousy and lust for more
That shattered peace and started a war
Broken siblings and the sound of drums
Ponies couldn’t believe what i’d become

Revolution tore the land
Mare and foal broken on the sand
Just a puppet war for my on gain
Nopony could deserve this pain

Down on Equestria lights are burning
Even without me the world keeps turning
If I could go back, I’d change my words
But time only ever keeps marching forward
For my crimes and my selfish ways
I’ll be trapped here for all my days
There’s not a day on the moon
That I’m not longing for you
