The Rapper: Nas
The Song: "U.B.R. (Unauthorized Biography of Rakim)," from 2004's Street's Disciple
Who It Was Written For: Rakim
Nas responded really well to J. Cole's "Let Nas Down." Why? Well, we can't say for sure. But it may have something to do with the fact that Rakim did not take too kindly to the tribute that Nas wrote for him. While Nas was simply trying to educate rap fans about Rakim's importance, he ended up revealing some personal things on "U.B.R." that Rakim didn't really want Nas to talk about. It resulted in Rakim calling Nas out for doing it. They eventually patched things up and moved on. But if you want to know why Nas is embracing the next generation, look no further than this song. Nas learned a thing or two from the reaction he got from Rakim after writing it.
