Rolling Stones made their career by copying from black music. You should not take their opinion on Hip Hop seriously. It's a waste of time. How come all these magazines have no specific criteria on how they review things?
When I watch a movie review I see a lot of reviewers breaking down the movie starting from the beginning till the end. I may not agree with them but at the very least they tell me the exact parts of the movie they don't like. Yet when it comes to music, none of these magazines review the lyrics, the vocals, the instrumental properly.
Just this one is good this one is bad cause we said so. Oh OK...
Like fukk them rolling stones, no dignity to even come up with their own name, just ripping off Muddy Waters
