The National Academy of Recording Arts and Sciences has added some new categories for next year’s Grammys, including an award for best rap song. “The rap arena continues to be strong and growing. There are more releases, more artists, more airplay and sales, and more importantly, there’s more creativity in that area.’ In addition, awards in the world music field have been doubled: Trophies will now go to best traditional world music album and best contemporary world music album.”
