I don't like rap
you know what I mean?
you rhyme all the time,
like from a bad dream?

it's so easy to do
to make up the words
to say them to a beat
and then pull all the birds

I am no rap star
I don't open my trap
because I told you before
I just don't like the rap.

Thought up and written in ten minutes, it is that easy to do, it's just simple rhyming poetry set to a beat, but these guys are making millions out of such simplicity.
