We've been interested in Windows Phone development for a long time, and the idea just recently came to us over the summer. We have made several long car trips of >4hours and neither of us have satellite radio, or a lot of data to stream music for hours on end. We recently discovered that the Windows Phone has a built in FM tuner as well as a GPS, so we figured there must be some way to combine the two to get a list of radio stations while you are traveling. Throughout the hackathon we did just that, and created an app that pulls your GPS location, turns it into a list of radio stations, and voila! The target users could be anyone who drives in a car for an extended period of time (soooo... everyone?), or someone who is just too lazy to find their own radio stations. Pick a genre and get listening!
