What happens when a location-based service like Foursquare and a radio streaming services like Pandora are mashed together? We end up with something like WahWah.FM. WahWah.FM, a German-based start-up, is a music service that lets users create their own radio stations by picking music on their own iPhones and simultaneously listening and streaming those songs to anyone else who'd like to listen.
Unlike Pandora and other services that may use algorithms and recommendations to pick songs for stations, every user is their own DJ and can choose which songs they will listen to and broadcast to their listeners. Users can tune into to other users all over to world to check out what they're listening to. Stations can be posted to Facebook to let friends know that music is being broadcasted. And there are even ways to interact with the listens to the stations each user has created.
WahWah.FM is a free service and is now available on the App Store. Check it out and start streaming.
