Two of the game's more lyrical rappers have bones to pick with each other.

Lupe Fiasco and Royce da 5'9" had been friends and had recently hosted a podcast together.

But something must have gone left because this week they've each attacked the other on wax.

Royce hit Lupe on Wednesday with the track "Silence of the Lambda."

"Your flow is redundant, I'll separatе your body from soul/Now your body is cold, spiraling out of control/Now you're over therе, body odor is pungent/For coming out of your body over assumptions/Look at all this passive aggressive pussying/All the past neglectful positions these pussies put me in/We them cool niggas bringin' food, liquor and fullies in."

Lupe quickly responded today on "Steve Jobs".

"Listening to your track record I can see you were skipping classics/I did it on my first one and delivered to the masses/Your songs are immemorable/Your verses are impenetrable/I ain't even listen to that diss record/I only fuck with you ’cause of your interviews/I ain't even trip when you called me a bitch/I was like, 'Look at Salem, callin' me a witch."

Royce vs. Lupe, who you got.
