Why Won't Big Sean Pick Up? Royce Da 5'9" Wants To Know On 'Keep It 100'

Royce calls out his fellow Detroit native on the new Slaughterhouse mixtape.

On his "Control" verse, Big Sean raps that it's "Detroit vs. everybody." But Royce da 5'9" may beg to differ, as new lyrics suggest that Sean has been avoiding the fellow D-Town native's calls.

The rhymes come on "Keep It 100," a solo Royce song that's featured on House Rules, the new mixtape from he and his Slaughterhouse groupmates, which dropped this week. As the song title suggests, the 36-year-old uses the track to speak honestly about some situations in his life -- both personal and professional.

At the 1:50 mark, he sets the stage by describing what it's like when people are constantly hitting him up to get to Eminem, before bringing up Sean:

"Shady got these industry n---as on some fiend sh-t/They use me to try to get to him, like a seamstress/ I tell a n---a quick to e-mail Paul/ And quit acting like a female dog/ Other than that, shout out my n---a Khaled/ You the homie, my n---a/ If it was up to me, you know bro would be on it my n---a/ You turned that Ross verse around for me in like a day/ While I'm blowing Big Sean phone up for a verse/ Feeling like, instead of this busy body sh-t with my family/ I might as well try for 'Ye"

It doesn't seem like a coincidence that Nickle mentions people using him to get to Em just lines before calling out the Sean for not returning his calls. The G.O.O.D. Music rapper linked up with Marshall in the studio in April 2013, during a session where Royce was also present.

Royce appeared on Sean's 2012 mixtape, Detroit, and the song "100," which also featured Kendrick Lamar.

Meanwhile, Khaled is still chasing that Em verse (unless it's on his upcoming album, I Changed A Lot), and Royce's Rozay feature has yet to be released.

Hopefully these two figure it out and get on a record together again, because their Detroit collab was too good for there to not be a followup.
