He did, woe, I remember when he uploaded it on his ovo blog. Thats why he took it down when it caught steam.
While every other song is still up there.
he removed it because it became an official single for sale... not just a soundcloud freebie. its #22 on the charts right now. The Hot 100 chart, not just the rap chart.
People ASSUMED it was a cha cha remix. Because it sounded similar, but the construction of the songs are nothing alike
