what's the name of that song soulja boy posted on youtube that was very very different from his usual sound?

In it he said "this that feel good music" and he was just walking the
entire video in what looked like a subdivision almost and one line of
the lyrics was "the world is yours the world is mine" and at one point
he messed up and walked backwards to where he was when he messed up
and continued. and i think he was playing the song on his cell phone
while he was shooting. it wasn't a very high production video. it
seemed like he just had his friend use his HD camera and record his
path while he was rappin with his song on the phone. I think it's
about a year or so old, the video.

someone gimme the name of the song or the link to the video.

ive tried looking through his videos already posted on youtube but
he's got so damn many! lol
