The Radio Search Engine does pretty much exactly what you could expect. Pop in the name of a track, genre or artist that interests you and this search engine will attempt to find if it playing somewhere around the world for you. If it can, you can listen to it there and then. If it can't find your choice it will find stations that are likely to play it shortly. The stations are from all over the world. About half are internet only stations and half are simulcasters who are transmitting their AM/FM station online as well. It is very simple and easy to use.
