I'd probably be the same if I was Em and all these numptys were constantly on at me who couldn't hold a candle to me... yeah it would probably bug me too. Also, he just took MGK to school with that diss track.
I didn't enjoy it very much. For being hailed as a 'return to his roots' most of the tracks are not in his style, his vocals don't even sound like his older stuff. A few of the tracks are an autotune away from being the worst of modern rap. I wonder how much Dr Dre had to do with the production given how different the stuff on Kamikaze is.
I don't think artists need to reinvent themselves constantly, and Eminem has up until now been fairly consistent outside of the slip all artists take into singing about their kids and things they regret (dude, shut up about your mom already, we got it 3 albums ago). I really miss his style on this one. After listening to kamikaze I immediately pulled up Revival and gave it a listen... I'd take revival any day.
