Mobb Deep‘s Havoc will never doubt Slim Shady’s greatness ever again. The hip-hop veteran has saluted Eminem for delivering a game-changing “Killshot” battle record.

Hav hit up Instagram this past weekend to praise Em’s lyrical powers with an unexpected co-sign.

Last month, G-Unit boss 50 Cent applauded Em’s record making history on video streaming giant YouTube.

According to reports, Em’s “Killshot” YouTube video had the largest debut of any hip-hop song in YouTube history.

The official audio of “Killshot” earned a record 38.1 million views on YouTube in the first 24 hours of its release on Friday. It now has over 72 million views on the site. YouTube said “Killshot” also had the third-highest debut of any song in the site’s history, and the track is on top of the site’s US trending chart. (Business Insider)
