"Don't worry I'm working on an album!" Eminem tweeted back in October. The song he released with that tweet, the seven-plus-minute, mostly acapella "Campaign Speech," met mixed reviews, but it showed Em could still rap his ass off, and could still shock and offend listeners (to the detriment of the song, in this case). The stakes are high for Em to shake off the rust and deliver on this album—he's several years and dozens of songs removed from his untouchable early 2000s peak. But as long as it includes at least one jaw-dropping "Rap God" standout moment, his legacy will be just fine. —Alex Gale
