A-hem.
"Hammer meet nail!"- As previously stated this is symbolizing that the hammer has finally driven the nail as far as it will go, and he is meeting what he has been… err… hammering on for so long. In literal terms- "Captain Hammer, meet the person you've been picking on for so long." I think.
DH sees the world as rioting, so he is simply telling the crowd their fate. ("Why can't they see what I see?'Why can't they hear the lies?/Maybe the fee's to pri-cey for them to realize/You're disguise is slipping")
Have you ever heard the saying 'Don't be a sheep, be a shepherd?' Sheep are considered stupid and DH is saying that society is blindly following whoever tries to lead them, and they've been led to failure.
Hence this is a musical, they threw many metaphors/simile lines in this movie. Following a legend that many people believe, DH is saying that it's society's fault that they've slipped, that they've "led themselves to the water" and they're going to drown (metaphorically speaking).
True, people did judge DH. But he's saying that no one's judging society; no one's putting pressure on them.
CH slipped when he taunted DH saying that "I'm gonna give [Penny] the night of her life. Just. Because. You. Want it. So… he started it!!!!!
Listen to Slipping again. He's not saying "anarchy", he's saying "an arcade". It's a funny line. Then I win/ Then I get!/ Everything I ever/All the cash!/All the fame!/And social change/An arcade!/That I run!
DH's goal is to rule the world. "The world is a mess and I just need to rule it!" He's getting what he wants, which is to rule society and fix it, whatever that may mean (this is why we need a SEQUAL!!!!!)
Not literally "burn". He has a death ray with him, so he's getting in the moment. He's saying that since he's evil the world will suffer under his command.
DH has been trying to be evil for some time, and he's finally getting his chance to tell the world they suck. Since everyone's cowering away and refusing to believe, he's basically saying LISTEN!
On an off-topic note it took me quite some time to figure out what an Australia is. (Mentioned in Brand New Day. It is a very SICK car that I now what.
So, he's not back-worded, you're simply taking the song literally.
