Why do I only like Jurassic 5?

I used to work with a guy back when Quality Control came out that felt the same way. He pretty much hated all hip hop before he had heard J5. It was just a matter of him never really being exposed to anything other then what was played on the radio or Mtv before that so he assumed that all hip hop involved guns, drugs and other ******** like that.
