Eminem was originally supposed to be on Joyner Lucas's hit track 'ISIS' as part of an exchange that had Lucas on the Shady track 'Lucky You.'

However, Shady was taking his sweet time delivering the verse, and Lucas ended up replacing him with Logic, who had been beefing with Lucas for some time.  Joyner explained how it went down:

"Eminem was originally supposed to be on ‘ISIS,’ Joyner wrote about how he was supposed to return the favor for appearing on Eminem‘s “Lucky You.” “I waited a month for his verse but at the time he was finishing his album and couldn’t give me a date, "Lucas typed. "So After i made amends with logic he invited me over to his house and i played it for him. He went crazy and knocked it out on the spot. That record will be 2xs platinum next year. Lol crazy right?"

Do you think Logic went nuts enough to justify bumping out Em?
