The cool thing about the "radio" is that you can "change stations". that is in effect what happens when you load the different "stations". The easiest way to manage all that used to be with the use of Digital Trucker's
Radio Station Manager. Windows 10 especially can be rather finicky about it, but Windows 7 can also. Once you get it set-up though, it is much easier to deal with the radio stations, and build a set of them that you like. There is a mod discussion thread link on the download page. You have to pay attention to the details with it. Using it on the CBS Radio (can't remember the correct name) can fix the date error in it that can CTD your game. Good stuff, that I wish was update-able, like a mod... lol
