For those of you that are not Manson fans (and I understand that, I'm only a casual fan) I'd like you to join in the irony here.
"This is the New Shit", the song absurdly-placed as the new themesong of a fairly-generic fantasy world with a lot of blood, is actually a song lampooning our consumer culture. The lyrics refer to the "new shit" as some fantastic new product or service that the consumer must buy for arbitrary reasons...not because they need it, but because it's new. It's a song about aggressive corporate greed and people guilible enough to buy into it.
Think about that a moment.
