If you're a fan of hip-hop and rap, then you're in luck. The Beat 102.7 is getting a new show, hosted by Funkmaster Flex, as well as a slew of new songs (some recorded specifically for GTA) and another new show DJed by Statik Selektah. Then there's Busta Rhymes, who will have another track featured other than his upcoming premiere of "Conglomerate."
On the other end of the spectrum, metal station Liberty City Hardcore is getting some fresh content with a new show DJed by Max Cavalera of Sepultura and Soulfly fame (click here for a sample of his brand of metal) and will feature new tunes, including artist Bathory. On Liberty Rock Radio 97.8, Iggy Pop will return as DJ, and the station will get some new tracks, and indie-rock Radio Broker, DJed by Juliette Lewis, will also receive some new music.
Interesting factoid: the new music and shows will play first, before the established music and shows, allowing the new content to have priority with players. So that's nice.
