A remix of Secrets, also known as Secrets ("The Hidden Orchestra in the Back of Your Alien Spaceship That Follows You While You Fly Around A Laboratory" Orchestral Rock Remix).
Kartsal's an appropriate image.  He seems to have lots of secrets -- in fact, for all I know Pumo could have originally titled the song Secrets as a reference to him.  But, that's not the reason I chose the picture.
I just love his hat.
