It looks like some kind of new content is coming to Grand Theft Auto V's multiplayer mode. Developer Rockstar Games today published a cryptic tweet that lists off four electronic music artists: Solomun, Tale of Us, Dixon, and The Black Madonna.

Right off the bat, this looks like a reference to new music coming to GTA Online, either in an existing radio station or potentially a new one. Back in December 2017, Rockstar added a Frank Ocean radio station, so there is precedent for new music coming to GTA Online.
