CuDi's unreleased track?

Yesterday I posted a video in which I claimed that CuDi had an unreleased track with some Kanye samples on it. However, now that I listen to it I realized that this was the intro from the Sky High Mixtape by DJ Benzi x Kanye West. So it makes me wonder if this was just another CuDi freestyle or if he actually using this track. Either way it was a nice rap. 

Here is the video 

And here is the song
