One of the discussions prompted by Kendrick Lamar’s new verse has been about the competitive spirit in hip-hop and the fact that it’s been lacking lately. So many of the best/most famous rappers are more concerned with brand partnerships and behind-the-scenes politics than they are with stomping out their competition or proving their superior skills. Kendrick basically challenged the best rappers to step up. Meanwhile, Eminem—who used to be the epitome of competition, technical skill, and rule-breaking in rap—has premiered an intense new song via a video game soundtrack.

Call of Duty: Ghosts drops on November 5.

UPDATE: You can now listen to the full version of the track via the Shady Records Soundcloud.
