I recently posted this in the 'greatest emcee' thread and feel it's relevant to the conversation you guys are having here...
My two cents: NaS
Without wishing to turn this into another monotonous Stillmatic appreciation thread, the trouble with Nas is that he can continue to drop clearly average albums right up until the day he retires and due to the fact he was responsible for Illmatic, albeit twelve years ago exactly in four days time, it is unlikely any self respecting fan of hip hop would remove him from their list of top five rappers.
His last few albums have been disappointing and he has made one truly abhorrent album along with a string of average outings yet he will always have ’the Illmatic factor’ ie- lauded for making a classic debut album irregardless of consistancy in terms of quality since.
In my opinion he is overrated by 2Pac fans but I still enjoy the good / classic joints he has made and no one can take those away from him.
