i mean, there are other "conceivable standards."

for example, nas doesn't really have many big hit records over the last decade. "made you look," "one mic," "i can" and "ether" don't stack up against what artists like 50 cent or TI or wayne or jeezy or busta have done from a popularity standpoint over that duration. not saying nas shouldn't be higher than those dudes, just saying it's a metric.
