Jok made this, pretty fun! Here's what he had to say about it:

"The song is from El Soldado, a rock singer not so well known here in Argentina (but well known nearby the studio location, called "MorĂ³n, aka The West". I know this may sound funny to you, he he). The song is about a tough guy who painfully fights his way through. But, in the end, all he wants is to be given that special zip (the name of the song) and just dream (sorry for the awkward translation!). But I chose the song because it sounded cool (it´d have been kind of embarassing to choose Ennio Morricone. Perhaps next time!)."
