I heard the rumour couple weeks back. It's funny that 400 Bars went over Exhibit C instrumental. Why? Peeps the words from Jay Elec,

That's why when you talk the tough talk I never feel ya.
You sound real good and you play the part well,
but the energy you giving off is so unfamiliar.

Essentially how I felt when Game went in on 400 bars. Jay Elec spitting prophecy, aye?

As for the collabo should be dope as long as it's natural. Game can come correct when he spits real shit ala Bang Along.
