James Newell Osterberg, Jr., better known as Iggy Pop (born on April 21, 1947 in Muskegon, Michigan), is an American singer-songwriter, actor and musician who is known as the lead singer of the rock band The Stooges who hosts Liberty Rock Radio 97.8 in Grand Theft Auto IV. He voices a fictionalized version of himself.
In between songs and the Liberty Rock jingle, Iggy often has his opinion about drugs, terrorism, women, today's music, and the time of day/weather in Liberty City. He rarely ends his opinions without throwing in slurs of vulgar language ("have a nice day sucking the corporate cock") ("well it's all shit, just plain shit") ("...a type of t'ai chi called fucking like a bandit. Great exercise man, spiritual.") He also mentions a few times of his station that, "I play what I wanna play and say what I wanna say." and, "I don't give a shit if you don't like these songs 'cause I do!" This means that he doesn't care what the FCC thinks about what he plays and what language he dishes out because he thinks of himself as a "freedom fighter" and is laid back against other radio stations that are "held by the balls" (so to speak).
