Well, this song I had a lot of time on my hands, and I FINALLY figured out how to make dubstep not only a bass, but a LEAD! Anyway, Phobos is one of Mars' moons. It is the [Greek] God of fear. This song is best for pumping it up because the sounds are meant for it and so are the basses, so PUMP IT UP!
P.S. BLOOD FOR THE BLOOD GOD.
