I'm My Own Master Now (Spirit of the Wolf Mix) is a youtube mix by one MonoChromium, not an official track. A good amount of music from the game didn't get onto the soundtrack release -- examples include the Hammerhead mini-boss music, Sundowner's outro track, and the piece that plays during the first two phases of Armstrong's fight, between EXCELSUS and the crater.
