When Nas is at his best (see all of Illmatic,) , he is one of the 5 best rappers in history. When he is at his worst (see Oochie Wally and You Owe Me) he is pretty damn aweful. Well it thankfully looks like Nas is bringing his A game to 2011. Exhibit A is his newest single the appropriatly titled "Nasty" which you can watch here: http://www.youtube.com/watch?v=sDpQzNCtEIg He has also had some very good guest spots of late including with Raekown on the track Rich and Black http://www.youtube.com/watch?v=a3YeByQEvZY and Ghetto Dreams with Common: http://www.youtube.com/watch?v=eajxVPJaq7g
