What Rap song am i talking about?

Theres a rap song i heard a few weeks ago as someone posted a link on yahoo answers, i think theres 3 verses and they are all black, theres no video. and i think its the second verse but the guy doesn't rhyme at all (purposely) and at the end of his verse he says something like (and i didn't even rhyme my verse) but its so real he doesn't even have to rhyme and he proved that point. I vaguely remember it possibly being a love song about a girl but i could be COMPLETELY WRONG. And the rappers are not mainstream *****'s, i think they are not very popular however real rap fans will know probably.
