Whats the name of the secret song in Shi No Numa?

Ok, this has been bugging me 4 a while now, does any1 know the name of the song that comes after u get the dead air achievement (If you dont know, The Dead Air achievement is when u open up the Comm room and hold X on the phone) if any1 knows the name of that song that would be great.

I don't want to be unhelpful, but what the heck is Shi No Numa?
