Player Phase Main Stage (Pre-Historic Moment) - SD Gundam G Generation Cross Rays OST

Theme that greets you for all of 5 seconds when you grind (because entering battle animations and pressing back is faster than the quickest Off animations).
I just now noticed how unfitting the gallery pictures I used were. Oh well. I only had them set up because there's no other place to put them.
