52. M.I.A., 'Arular'
M.I.A.'s 2005 debut is both politically and musically radical, with the British emcee delivering biting, often nihilistic revolutionary rhetoric over tracks that blend rap, dancehall, club music and harsh British electronica into some of the most raging bangers of the decade. It's dark stuff, but M.I.A. has a wicked sense of humor, dropping bitter zingers into intense tracks such as "10 Dollar," "URAQT" and the single "Bucky Done Gun."
