The collaboration-heavy field includes B.o.B (featuring Hayley Williams) with "Airplanes," Drake, Kanye West, Lil Wayne and Eminem with "Forever," Eminem with "Not Afraid," Jay-Z and Swizz Beatz with "On to the Next One," and Kid Cudi (featuring MGMT and Ratatat) with "Pursuit of Happiness." The category includes nods for two legends, Em and Hov, who boast acclaimed late-career albums, but the recent focus has been on two big-in-2010 newcomers: Drake and B.o.B.
