Don't expect a collab between 2012 alum Danny Brown and 2011's Mac Miller anytime soon. Brown told Rolling Stone last December, "He's the worst guy around. Don't get me started... If I see him, I'm just going to have to apologize to him, like, 'Man, I just want to apologize for hating you so much. Because I'm not going to stop. You're probably a cool guy. I don't feel violent in any way, but I really hate you. I hate your music, man.'"
