Chance The Rapper-Untitled

Holy shit, this isn't real. Chance released 2 songs yesterday and a previewed a 3rd one today on Sway In The Morning. It's happening, something big is coming. This song doesn't have a known title yet, but it's my favorite of the last 3. Chance can be heard saying that this song is "very important to [him]." What does it all mean???

UPDATE: It took me a few more listens to realize it, but that's J.Cole at the end! Finally, a Chano x J.Cole song.
