My head has been all over Peter/Lydia lately, so this is the song:

Disturbia by Rihanna

It's a thief in the night
To come and grab you
It can creep up inside you
And consume you
A disease of the mind
It can control you
It's too close for comfort

Put on your pretty lies
We're in the city of wonder
Ain't gonna play nice
Watch out, you might just go under
Better think twice
Your train of thought will be altered
So if you must falter be wise

Your mind is in disturbia
It's like the darkness is the light
