Repent! Repent! The Apocalypse is nigh! And so is Amazon’s adaptation of Terry Pratchett and Neil Gaiman’s tale of Armageddon, Good Omens , where the end times start with the birth of the most adorable little Antichrist ever. Now, to bring their Devil-loving music to the masses, the most talkative group of Satan-worshiping nuns in the world have released their own music video celebrating the arrival of their little Dark Lord, who comes with fire, blood, and that new baby smell.

When the ground below rips open and darkness fills the skies above, the streets and rivers will run with blood of the innocent and guilty alike, as Heaven and Hell will meet on the battlefield for a final showdown. Unless of course the unlikely duo of an angel and a demon can stop the whole bloody mess from happening, in the upcoming adaptation of Good Omens. But as readers of the beloved novel know, not everyone on Earth is eager to stop it.

The Chattering Order of St. Beryl, who helped bring the Antichrist into the world (and also helped mess up Satan’s grand plan eeeever so slightly), have been welcoming the coming of the end with song. Now to spread their demonic gospel they have released a music video for their hymn, “That Brand New Baby Smell.” And they got a very special someone to make a cameo.

As for this sweet/sinister a cappella song, which features some great Easter eggs from the novel, they might worship the Devil, but The Chattering Order of St. Beryl sound like angels. Of course this is now going to be stuck in our head for weeks, which is probably what they wanted.

As if worrying about the end times wasn’t already hard enough without an earworm. Though that’s better than the actual worms we’ll probably have in our ears during the Apocalypse.

Good Omens comes to Amazon Prime on May 31.
