In his conversation with Sway Calloway of Shade45 Fat Joe talked about the verse Eminem recorded for his upcoming album “Family Ties”:

Imma give you one line Eminem says in a song. It’s the most disrespectful song on the album. Em has not rhymed like this in years. He says he’s “a unicorn in the human form” but the illest line he said that’s stuck in my head was “I’m just a cracker with a barrel, armed to the t, Anderson.Paak, rest in peace Afeni Shakur and her son Pac”. Crazy! This boy’s going too crazy! There is someone on the song too. It’s so legendary that in 10 years they will make a play of it.

Since then, though, the tracklist of “Family Ties” was revealed so we know the title of Eminem’s track and the name of another artist featured there: Lord Above (feat. Eminem & Mary J. Blige)
