Just to jump in here, I did a lookup on this release, for some reason and I will poke around more for why, this release of The Way of the Fist
from 2007 seems to only be available for US Spotify listeners currently.
<album><name>The Way Of The Fist</name><artist href="spotify:artist:5t28BP42x2axFnqOOMg3CM"><name>Five Finger Death Punch</name></artist><released>2007</released><id type="upc">00810067011778</id><availability><territories>US</territories></availability></album>
Now as for the new yet to be full release of Got Your Six has a release date of September 4, 2015, maybe there was a slight issue over the releasing of the single Hell to Pay in your Listening region, not sure?
Anyway here is Way of the Fist if you just happen to be a U.S. Spotify listener currently.
