 The last song is "Smashed to Pieces In the Still of the Night", they found this written on a wall in Vienna and used it for themselves.They were once driving and all the lights were gone except for the headlamps, whilst a train came past and the driver, apparently, started to descend into madness.The journey goes into the middle of the desert and it ends by your doppelgänger confronting you saying "how long do you mean to be content?."
