Nas "Who Killed It?" (2007)
Album: Hip Hop Is Dead
Label: Def Jam/Columbia/The Jones Experience
Producer: Salaam Remi, will.i.am
Some MCs have a thousand voices they can slip into to portray different characters and perspectives, but all Nas needs is one voice: that incredible Nas voice. So it was bizarre to hear Nasir Jones slip into an Edward G. Robinson impression on "Who Killed It," a laughably ridiculous detective story that sought to find the culprit of the supposed genre-slaying at the heart of his 2006 album Hip Hop Is Dead. Nas's catalog has its share of bad ideas, but there's nothing as straight up embarrassing as listening to his voice crack as he says, "She's a real looker/They say her old man's a bootlegger!"
