If this was like 4 years ago, I'd agree. But over the years I've learned that all Atmosphere seems to rap about is his past drug addiction and past woman that he bitches about. He's amazing for that genre of rap, I just feel like hearing the same topic in every song gets old. It's like Immortal Technique, his first two albums were amazing. Now we all get it, he hates the government. His new mixtape was great, then i stopped listening to it because it's the same message he's been spitting for years.
Then again, my favorite 'underground' rappers are Aesop Rock and probably Weerd Science (ironically enough, his newest album is all about his drug addiction, but he makes light of it as opposed to the overall depressing feeling that Slug gives off.)
