Are there any hidden radio stations on the radios?
Solution 1:
I think there was something about the radios that the developers decided to left out the final version, which is sad, imo. There are a few radios in locations with difficult access, almost hidden and very hard to spot. I remember one in Thousands Cut that's pretty much "out of the way" of any story missions or side quests.
Solution 2:
I've definitely heard two different talk shows and they were hilarious, but I skimmed over them without thinking. Haven't been able to listen to them since.
