Rockstar Games, alongside a few artists, has taken to social media to tease upcoming musical content for GTA Online — a move which lends some additional legitimacy to the recent Nightclub DLC leak. Nothing has been confirmed yet, but there are too many pieces that fall into place.
In a tweet only just posted, Rockstar revealed the names of four artists — Solomun, Tales of Us, Dixon and The Black Madonna — whose music will be featured in GTA Online sometime this summer. One of the artists, The Black Madonna, also tweeted about the collaboration albeit with a different piece of artwork.

While the image used by The Black Madonna is composed of the Los Santos skyline with a retro 80's neon purple and pink filter, Rockstar's image uses minimalist symbols on each side of the artists' names. These geometric shapes are key to why this might also by extension lend credence to the nightclub DLC leak.
