Yasiin Bey, fka Mos Def, was arrested in South Africa last week for trying to use a World Passport to leave the country. He’s still being held in Cape Town, and tonight, the rapper has shared a freestyle addressing his situation — with a little help from Kanye West. West posted the message on his official site, kanyewest.com, and Bey’s lyrics reference Kanye’s recent songs “Real Friends” and “No More Parties In LA.” Listen here.
