Love this idea.
After they sold TW3 more than 10 mil copies they are lacking money? I don't think so. Also, radio is one of the easiest features to make and it is largely independent from the main game development: it is almost stand alone feature. You just need a writer with a good sense of humor, actors and sound recording. Dialogues are much harder to do due to branching and situational context.
It depends on who your actors are. Don't invite famous Hollywood stars and you're fine. And, in comparison to dialogues, radio shows are linear and don't have branching. They are literally 3-4 times cheaper than dialogues of the same length. The only problem with radio shows is quality. For example, Fallout 3 radios were borefests.
The thread's about a radio talk show, not music. Did you even click the link? You should; Deb is the best and CDPR including something that gives the world that much personality would be a point in the game's favor and give them another avenue for reactivity. Music stations are a terrible idea, though, and tend to cause all kinds of rights problems. One of the GTAs had to be removed from Steam for awhile to remove some of its music because of expiring song rights, and Hitman: Contracts was in a licensing mess because of its music that kept it off digital distribution sites until 2014.
