Radio in Grand Theft Auto: Chinatown Wars is substantially stripped down from that found in previous games, due to the size limitations of the Nintendo DS cartridge. There are five radio stations, yet none of these feature any voice tracks, being purely instrumental. Radio stations in vehicles can be changed through buttons on the touch screen. Interestingly, the radio stations from Grand Theft Auto IV are advertised on billboards throughout the city, yet none are accessible to the player. All the stations are named after real artists of bands, most of whom contributed, albeit with instrumental rather than vocal songs.
