Uh, I don't give a fuck about what other people think of the artists I listen to. As long as Em keeps releasing music I like, I'll keep listening to it. I know there's not much chance of him releasing an album that's as good as any of his 'top three', but I still find his new music enjoyable.
It doesn't matter anyway, when the majority of people look back on Em's career they'll focus on the positive aspects of it. Just look at MJ, and all the bad press he's had over the years, yet he's still viewed as a legend. Just look at any well-loved artist that has released mediocre music late into their career (which most have). When I think of Eminem, I think of him in his prime and the music he's been releasing since 2009. I don't think of him from 2004-2008, in other words (lololol) I don't think of him when he was fucked up on drugs.
