The radio stations in GTA SA cannot be deleted. GTA:SA uses a new technique for the radio stations. Whereas Vice City used a single massive audio track per radio station, SA splits each station into about 150 audio clips, which are strung together randomly according to some rules. The audio clips are things like:
* Station idents
* Announcements about in-game events (e.g. weather, travel)
* General chatter
* Phone-ins
* Commercials
* Programming (mostly songs)
Commercials are not included with the main radio stations, but in a separate file.
The programming is further split up. Most songs consists of one audio clip for the main body of the song, and three different intros and outros, each with different chatter over them (or no chatter).
