Complex posted an interesting review of the track (not the one quoted in the OP).
I'm not sure on the rules for posting links and what not.. so I'll just post some quotes:
"As we've seen this week, music consumption and criticism is a different ball game in 2013. What's most subversive aren't Eminem's jabs at celebrities, but a 20-year-old's raunchy stage performance [Miley at the VMAs]."
"'Berzerk' is understandably difficult to grasp. Popular music has been so inundated with EDM and trap sounds that the single's aggressive homage to 1980s hip-hop is in complete contrast to the sound of today's music."
"But Eminem’s singles were always tough to digest. "My Name Is" was not congruent with the Swizz-led sound of Jay Z and DMX. Neither was "The Real Slim Shady" or "Without Me" in line with Irv and Jeff. But in an era before social media and instantaneous, communal reaction to big events, Em's natch for attacking celebs for things they did months ago was titilating, intriguing, and relatively timely. His first singles used to be like a News Feed in song form, and he benefited greatly from it. The work he put in then to establish himself as a top tier artist, and the 100 million-plus records sold as a result, is why his new music matters now. After 15 years of dominance, the mere existence of a new Eminem song is an event, and no amount of backlash against how it sounds can deter that."
"So why will "Berzerk" be successful in spite of any sonic criticism? For one, it's Eminem, but as stated earlier, calling Eminem successful for selling a lot of records is like giving Tom Brady a pat on the back for throwing one touchdown. It's cool, but more is required by virtue of the standard he's set for himself. The thing is, "Berzerk" meets that standard, and if anything, the one part of the song no so directly inspired by the ‘80s—its distinctly Slim Shadian chorus—will be right at home on radio. The familiarity of Eminem’s voice has credibility and leverage in the pop realm that’s hard to compete with."
"This is not to say that mainstream gratification is the end-all, but the inevitable success of "Berzerk" in that arena is why Eminem will remain relevant to the greater conversation. And like all the other Eminem albums preceded by singles that made conservative rap fans grimace, the long player will deliver elite, undeniable bars. So, yes, he’s back."
