Nas is absolutely the best. As far as just flat out lyricism goes, just straight up being a technical master of pure lyricism, there's only a handful of names you could even mention in the same breath as Nas and they are...Rakim, Eminem, Big Pun and that's about it. And Nas' music isn't boring. It's only boring if you're not listening to what he's saying. If you're someone who just wants something to ride to and nod ya head to and keep you company on your way to work or while you're running on the treadmil in the gym and that's all music is to you (which is absolutely fine, I've realized over the years that most people don't take music as deathly serious as I do and I'm sure many of the ICC do), then you might find some of Nas' stuff to be boring. But if you're one who listens to the artist and what they have to say then Nas' music won't be boring to you. The content will keep you interested. Nas' best verses are endlessly complex and shift through wide ranges of various topics at the speed of light with uncanny ability and anyone willing to keep up with him, on the journey's that his verses are, will have their attention fully occupied the entire time.
