Cozz's sophomore mixtape Nothing Personal is a pretty good indicator of his MC skill set, but you'd be hard-pressed to find a moment on that project in which he snaps as hard as he snapped on "Let Em Know".
Production on "Let Em Know" is provided by Meez, who lives with Cozz and produced all of Nothing Personal. The beat is eerie and expertly crafted but nothing spectacular in of itself. The beat is basically Meez throwing Cozz an alley-oop... Cody Macc throws it down like '00 Vince Carter.
I dip low, real low 'cause them niggas is foes
They might act like your friend but then hate on the low
I said, you know what, I'm just gon show up and blow up
I don't need no co-sign but hol' up, cobra
