You probably felt on your own the frustration that comes with not being able to remember the name of a particular music track playing at the radio. In this case you might want to use Audiggle. This is an audio recognition software which can tell you the song and artist name of anything playing on your PC (or through microphone). It’s enough to play a track for a few seconds and you’ll get the name of the track and the artist.
In case you would like to try it, you can get Audiggle here.
