If one is going to fire off one of the most popular diss tracks in recent memory, one may as well secure the bag while doing so. While Eminem's "KILLSHOT" has earned the hearts of fans (though vocal critics like Lord Jamar and Akademiks remain relatively unfazed), the initial release was largely contained to Youtube. While that's well and good for the masses seeking universality, who looking to add the IllaDaProducer laced track to their playlists were left waiting for the day of reckoning. 

Now, the day has come. Eminem's Machine Gun Kelly diss has joined "Rap Devil" on all official streaming services, meaning one can theoretically line Spotify, Tidal, or Apple Music with a chronological timeline of the ongoing feud: Tech N9ne & MGK's "No Reason," Eminem and Royce's "Not Alike," MGK's "Rap Devil," and of course, "KILLSHOT." A brief, but memorable tilt that has come to emerge as one of the year's most memorable narratives. 

Many believed Eminem had hung up the katana after "Like Toy Soldiers." Who'd have thought he'd be once again involved in hip-hop beef, after dropping a surprise album, no less? Next step: Relapse 2.
