I was thinking you should add a list of song's to play on the Radio. Like you can press e and switch to Radio Station (someone talking) to Radio (a list pops up and you play songs from the list that Miaw has added) So you can play some of them, maybe some cod 5 nazi one's and that.
I'm not entirely sure it's possible, but it would be a cool idea as radio hosts are often not on there so it's a waste of cash mostly.
