This song is obviously written from Lucifer's (aka the devil's) perspective. When he was cast out of heaven, he was forced to roam to and fro about the Earth. As he fell from Heaven, he passed the back side of the moon, which also makes you understand how dark his world is now. Once upon a time he was the most powerful angel in all of heaven and had millions under his command. Now he's alone, but wants to let you know that he understands how loneliness and sadness feels. So come join him if you're sad and lonely. To hang your head is also to bow your head which signifies servitude.
