Rest of song:
[Verse 1]
Em G D
I'm waking up to ash and dust
A Em
I wipe my brow and I sweat my rust

I'm breathing in the chemicals

I'm breaking in, shaping up, then checking out on the prison bus
Em G D
This is it, the apocalypse
A *
Whoa-oh
[Chorus]
Em G
I'm waking up, I feel it in my bones
D A
Enough to make my system blow
Em G
Welcome to the new age, to the new age
