Since Ana ALREADY guessed it, I figured I'd keep chugging along.

This one was "Build Our Machine" by DAGames!  Man I listened to it RELIGIOUSLY over the summer.

Okayyyy next one

Difficulty: Hard

(AND THAT MEANS EXTRA LYRICS WOOO)

This is it!

Now we've found it, I'm astounded

Every town will be surrounded

By a throng of marchin' death

Delicious the riches, they glisten ahead

It's a craze!

They'll devour every hour

Of these endless, non-progressive inundations of their kind

And lucky for you, you're the next one in line

When I'm [LINE REDACTED BECAUSE IT HAS THE TITLE]

No one can stop me, I dare you to try

The dead are infused with sensational groove

And they're comin' for you now

There's nowhere to hide

I love envisioning one certain character singing this even if it doesn't 100% match.  Season 3 of Chaos Club gets WILD, y'all.
