The first verse in Mathematics by Mos Def.

[Verse 1]
Yo, check it
One for Charlie Hustle, 2 for Steady Rock
3 for the forthcoming live future shock
It's 5 dimensions, 6 senses
7 firmaments of heaven and hell, 8 Million Stories to tell
9 planets faithfully keep in orbit with the probable tenth
The universe expands length
The body of my text possess extra strength
Power-lift the powerless up out of this towering inferno
My ink so hot it burn through the journal
I'm blacker than midnight on Broadway and Myrtle
Hip-Hop passed all your tall social hurdles
Like the nationwide project-prison-industry complex
Working-class poor: better keep your alarm set
Streets too loud to ever hear freedom ring
Say evacuate your sleep, it's dangerous to dream
For ch-ching, cats get the "cha-pow!" You dead now
Killing fields need blood to graze the cash cow
It's a numbers game, but shite don't add up somehow
Like I got, 16 to 32 bars to rock it
But only 15% of profits ever see my pockets like
69 billion in the last 20 years
Spent on national defense but folks still live in fear like
Nearly half of America's largest cities is one-quarter black
That's why they gave Ricky Ross all the crack
16 ounces to a pound, 20 more to a ki
A 5-minute sentence hearing and you're no longer free
40% of Americans own a cell phone
So they can hear everything that you say when you ain't home
I guess Michael Jackson was right: "You Are Not Alone"
Rock your hardhat, black, cause you in the Terrordome
Full of hard n****s, large n****s, dice-tumblers
Young teens and prison greens facing life numbers
Crack mothers, crack babies and AIDS patients
Young bloods can't spell but they could rock you in PlayStation
This new math is whipping motherfrickers' arse
You want to know how to rhyme you better learn how to add it's mathematics.
