Amusing. I think it's definitely funnier as a video, though if you really are freestyling, bravo! I see what you're trying to get from this, and I think a little more effort could have been put into marketing yourself as a rapper for hire. Three things I would've done:
1. Make it longer (you talk through half of it)
2. When you do flow, bring the backgrounds up - show us how you work with the music and that this wasn't just a beat poem with a radio on in the background.
3. Include scripted material - like I said, well done for off-the-cuff lyrics, but (as far as NG is concerned) I don't see a lot of people throwing beats at you and saying 'okay, now freestyle'. Showcase your talents as a storyteller, too.
Of course, this could just be a tongue-in-cheek number and I missed the point altogether.
So, I'll defer to my first impression:
Amusing!
