The first Grand Theft Auto has seven radio stations and a police band track, which can be heard once the player enters a car.
The game's main theme is "Gangster Friday" by Craig Conner (who also played all instruments on the track). It is credited to the fictitious band Slumpussy, appears on N-CT FM, and will be the first song the player hears upon starting the game. With the exception of Head Radio FM, the names of songs or the radio station names are never mentioned in-game. However the soundtrack is listed in the booklet which comes with the game.
On the PC version of the game disc, the radio station audio is stored in standard CD audio tracks. As a result, PC players can remove the CD once the game is loaded and replace it with an audio CD. The next time the character enters a vehicle, a song from the CD will randomly play.
The radio stations can also be played outside the game by putting the game disc into a normal audio CD player, as long as track 1 (which contains the game data) is skipped over.
