About this track:
This is one of the stage tracks. For those who aren't familiar with the Tears of the Machine soundtracks, the stage tracks follow a simple principle: they're actually made of three separate loops, one that plays when you're not fighting, one that plays when you ARE fighting, and one that plays during boss fights. These three loops make up pretty much the same track, it's just a way to create immersion during gameplay with the music reacting to your actions.
