Eminem & Tech N9ne New Music Collaboration Confirmed: 'Speedom (WWC2)' Payback, 'Best Rapper I've Ever Heard' Praise [WATCH]

Several fans were impressed with Tech N9ne's recent Special Effects collaboration featuring legendary Detroit emcee Eminem entitled "Speedom (WWC2)." But get ready - another epic duet between the two hip-hop icons is already in production!

Apparently, the Strange Music hypeman already contributed another verse for an upcoming Slim Shady hit. During a recent interview with KS 107.5 backstage at Summer Jam in Colorado earlier this month, Tech revealed:

"I paid him back already... I think - I did the verse. I hope they use it. That's all I'm gonna say."

Tech previously confirmed that Em agreed to work on a verse for "WWC2" for "nothing but a swap." Well, the "So Dope" singer stuck to that promise!

And some people thought that the 42-year-old MMLP2 superstar was officially retiring from rap!

The former Left Field Woodie Award winner also discussed working with Eminem on his latest record:

"I hold him as the best rapper I've ever heard... I expected him to do it, but it got down to the wire. My album was already in mastering. On the third day of mastering, he sent it already mastered."

Basically, the infamous "Rap God" just wanted some feedback and approval:

"He called me and he was like, 'Man, I hope you like it; I hope it's perfect.' And I listened to it and it was beyond perfect. Because I sent him me and Krizz Kaliko's verses some months before, I only wanted 16 bars, and he gave me 23, 24, something like that. So he really felt it."

So stay tuned as more details develop - does this mean Shady's coming out with another record sometime soon?

Meanwhile, Tech's already working on yet another 2015 release entitled Strangeulation Vol. II.
