nas says there is no best rapper alive.

Yeah, i just read an article where nas says you can not really call any rapper the best or the greatest....
Below is what he had to say.

"There is no best or greatest MC. Should never happen, doesn't make sense," he said in a blog post. "It makes sense temporarily when you're striving to be number one. It makes sense for [the fans] to see that, but you have a long run to be the greatest. To me, people already felt like they were [the greatest] in more ways than they should have and I think that hurt them. There is no greatest of all time. We won't know that until we're 60 years old. I think there will be like four to five great ones at the end of the day, but there will be none that's greater than the other. Impossible...[Jay-Z] is the one that smacks everybody in the face that's out there and wanted to say what he wasn't and what he couldn't do. The challenge is that people always count you out and even when you have a hit record and put out a hit album, you're gonna have people dissing you. I think he's showing you: I won't be stopped ever. And that's motivation for everyone else." (VIBE)
