No experience with rap, but this is too ridiculous for me to at least not make an attempt.

I'd say it's pretty Goenka-like based on what I know from a retreat and my readings. There may be one or two inaccuracies.
I am Goenka, my voice is deep.
When I chant it soothes and comforts.
Only way to measure progress: equanimity
Don't care about your maps and your shambles.
I brought vipassana back to India
Then to the west, didn't momma tell ya?
I have 250 centers across the world
Who even knows you? Yea a bunch of nerds.
I watch the body in perfect equanimity
If a thought arises I ignore it -b*tch!
Thinking is more suffering, I thought you would know.
That's not how you meditate, make a mental note.
They ask me if I'm enlightened, I go -say what?
That's anohter attachment, just purify your mind.
Check out this sutra of perfect wisdom:
It says there ain't no such thing called arahat.
