Yeah it's an unbelievable track and for sure in my top 10. The energy and lyrics of Mos Def are something that actually astounds me in disbelief at how good it can be. Mathematics gotta be in the top 10 too, it's got everything right.
Recently a hip-hop style has been trending, "phonk." Odd name, but the music is really cool. It's more common in Soundcloud and certain Youtube playlists; in fact, I first found it through "dark trap" playlists.
