Will XXXTentacion or Ski Mask the Slump God appear on the GTA 6 soundtrack?

Market context

Ski Mask the Slump God went on Instagram and told fans they'll hear his music and XXXTentacion's tracks while driving around Vice City. Both rappers came out of Broward County and defined the South Florida SoundCloud rap wave, which fits a modern Leonida the way Miami bass fit the original Vice City in 2002. There's even an XXXTentacion track literally called "Vice City." But Rockstar hasn't confirmed a single soundtrack detail, and radio station reveals always come late in the marketing cycle. Either Ski Mask just leaked a licensing deal, or he's talking about a conversation that hasn't been signed.
