I was driving from Wisconsin to Virginia this past weekend and had this idea... I had the unfortunate task of driving the U-Haul that was probably older than I am while my girlfriend drove my car. I had to be pretty concentrated on the road so finding a radio station from county to county just became too much of a hassle and I ended up sitting in silence for much of the 14 hours. Idea : An app that you put your route into, select your genre of choice and it gives you a list of radio stations along that route so you don't have to suffer through searching and missing potentially good stations because they're on commercial when you browse past (as I'm sure happened to me many times). As said in the subject, this is free for the taking. I think it would be a popular app.
