The opening track on the new Iluvatar album has the sound of a radio tuning to different stations, and I know this has been done throughout the years. Off the top of my head, the opening of Be Bop Deluxe's "Modern Music" has a radio being tuned to different stations, all of which play snippets of different BBD songs (in between static). I can't think of any others now but I kinda recall Pink Floyd doing this and maybe a couple of other bands.
