Dont know if its in the game already, because i do not currently own the radio as i don't think it seems worth it as of now. But it would be a cool feature to be able to create playlists with your custom ids so you don't need to input them every time. Also it would be nice to have a playlist on the radio with the in game music so you can just listen to your favorite layer music anywhere.
