Does gta online support custom radio stations?

The provided Wikipedia entry for Grand Theft Auto Online gives an overview of the game’s release dates, platform availability, and basic gameplay features, but it does not mention any support for custom radio stations. Because the source does not discuss the ability to add user‑generated or local audio files to the in‑game radio, we cannot confirm that such a feature exists. To determine whether the game supports custom radio stations, one would need to consult additional sources such as official Rockstar documentation, community forums, or reputable gaming news outlets.
