Diss tracks aren't supposed to do huge commercial numbers.

But Eminem's Machine Gun Kelly diss Killshot was viewed 38.1 million times on YouTube in its first 24 hours. That's the most in Hip Hop history, and only trails K-Pop band BTS's "Idol" (56.2 million) and Taylor Swift's "Look What You Made Me Do" (43.2 million) for all genres all time.

Eminem's good buddy 50 Cent had a bittersweet reaction to that news.

Do you think Eminem's success will encourage more lucrative rap beef? 

And do you think Eminem will grab a Grammy nomination for a diss track, like Drake did with the Meek diss "Back To Back?" If Em does, he's made it pretty clear he won't show up for the teleacast.
