i thought the begining of the song "Pulse of the Maggots" by Slipknot had something to do with NWO -

"..This is the year where hope fails you
The test subjects run the experiments
And the bastard you know, is the hero you hate
But cohesing is possible if we try
Theres no reason, theres no lesson
No time like the present, tell me right now
What have you got to lose, what have you got to lose
Except your soul... Who's with us?!
.."

"..We-we are the new diabolic
We-we are the bitter bucolic
If I have to give my life you can have it
We-we are the pulse of the maggots.."

"..We fight til no one can fight us
We live, and no one can stop us
We pull when we're pushed too far
And the advantages is
The bottom line is
We never, had to fight in the first place
We only, had to spit back at their face
We won't, walk alone any longer
What doesn't kill us only makes us stronger
Do you understand.."

I'm surprised to see no one has mentioned Hypocrisy yet, their song "Eraser" is practically crawling with reference to MK ULTRA.

Lyrics-

Here it comes to subject the terror you forgot
No memories from the past
The unexplainable starts to appear
As your sub-consciousness begins to come back again

Reality fades away
You try to find a solution
Here it’s coming now, indecision
You’re free but you can’t see through the confusion

[Chorus]
There is no time
No time to regret
The eraser’s coming for your life
You got to run
Stay away from the light
The eraser’s here to twist your mind

Feel your soul connected to the universe
The solstice is complete
They controlled your thoughts
You will remember now, what it’s all about

Twist the end around, violation
It’s burning deep and twisting under your skin
It scares you forever
The proof you will find in your dreams


Interesting to note that it is mostly heavy metal acts that sing about this.
