RoamDial

RoamDial is a free web app for dropping in on live radio from around the world. Stations are laid out by genre as a 3D particle galaxy you can wander; press play and it lands you on a random station, or browse by country and genre instead. About 35,000 live stations come from the community-run Radio Browser directory, with places from GeoNames. Save stations, share a link, and add your own stream by URL. If one stream fails it tries the station's next one. There are no accounts and no ads, and it works in English, Chinese and Japanese.
