From what we have seen the game is filled with swearing and sexual innuendos. Having gansta rap with explicit lyrics can be expected at this point. I don't care about music and artists per se, just the chosen artistic direction - its not what is generally expected from the genre and to me feels like attempt to get a bite of GTA audience. If these aspects are overdone the game can feel too juvenile and edgy.
I don't know that the chosen artistic direction is quite as obvious as you think. Obviously the game is supposed to be "edgy," I mean, it's based on Cyberpunk 2020 which was an incredibly edgy tabletop RPG. Juvenile, though? Not sure I agree with that. I swear like a sailor in real life, as does my SO, as does my family and friends. It's normal.
Swearing does not make a project or game or movie juvenile. From what I saw in the gameplay so far, curses are mostly used in appropriate contexts. Can you give me any examples of an "immature" use?
Rap is only one of the many types of music that will be in Cyberpunk, and from what I've herad, the others are bloody amazing. You heard Marcin Priavldflasblytz (can't spell his name ever), the composer? He posted snippets of the game's soundtrack on his Twitter. Sounds great.
I had other thoughts on the topic that I'd mentioned in my other post (hopefully you read it before it got thanos snapped) but I don't remember them, so I'll leave it at that for now.
