Nas Discusses Greatest of All Time

I wouldn't necessarily agree with Nas on the statement that Hip Hop is too young, but I do strongly believe there is no "Greatest of All Time."  Obviously there are a few standout artists that have changed the game tremendously and deserve to be in the discussion, but it's a matter of personal opinion.  One person may bring up an MC that another doesn't even have in his/her top five. You can't pinpoint a specific artist and bring up factual statistics.  Album sales are practically irrelevant nowadays, so comparisons between rappers from one decade to another don't hold up.  What makes an artist great is different depending on who you ask.  Besides...what does it matter??
