Needle Trax is the number one music retailer in Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories. There are two stores located in Downtown and the North Point Mall in Vice Point respectively. One store is located in Portland View, Liberty City. The Downtown location in 1986, the setting of Grand Theft Auto: Vice City, would later become Rock City, and the North Point Mall location would later become Vinyl Countdown in 1986.
The name of the business is a reference to the term needle tracks, which refers to the discolored marks on a heroin user's arm after the injection site becomes infected. It is also a reference to the "tracks", or grooves, on the surface of a vinyl record which the needle runs through.
