What happened the "O.G." track Wale?

So I was listening to Wale’s album snippets and i was confused as to why this joint ain’t on it. Definitely better than everything else I heard which is saying a lot cuz the album don’t sound too bad, it’s looking alright, but this joint would’ve put it over the top. This joint is too crazy…………
