X is the realest rapper we have ever seen. I know cats will fight it tooth and nail but he is the closest to doing everything in his rhymes. From robbing, stealing, doing bids, being homeless, being on drugs, fighting inner demons that he TOLD you he was fighting.
He may not have been the dopest MC or most lyrical, but to me is in the same vein as some of Pacs work, where wasn't overly complex but because of the emotion he put into, like other posters said you could relate. When I was on the super grind I put X in and nothing could stop me. I still run to X and DBlock 3-5 times a week.
