A few days ago, Mas$e reacted to a strong co-sign from radio veteran DJ Cosmic Kev.

Last week, New York rap veteran Fat Joe reacted to Ma$e’s return and recent “The Oracle” diss song.

“I was entertained by that,” Fat Joe said referring to the Ma$e and Cam’ron feud. “But you know Ma$e is Kanye West’s favorite rapper. You know Ma$e is Eminem’s favorite rapper. Ma$e is nothing to be f*cked with. Dipset is guilty of it. I’m guilty of it. We’ve all been playing with Ma$e. I was very, very surprised [when I heard ‘The Oracle’] because it’s very, very hard. I went to jail for four months and when I went to the booth, I almost cried. I was off beat. I was like, ‘Oh my God. I fell off.’ And by like the second day I caught it but I thought I lost it. … The problem with Ma$e is we don’t know. Is he in the fight or not? He’s in church and now he’s back. Then he’s back to church. We can’t really hold onto something. Like, ‘Yo, this my n*gga, yo, I’m rocking with him,’ because we don’t know.” (“Everyday Struggle”)

Recently, Dipset’s Jim Jones revealed former NBA great Allen Iverson personally reached out to end tensions toward Ma$e.
