Audiggle
Audiggle is a new software application that brings something that was previously privative to iPhone owners into the hands of desktop users: the recognition of songs as they are playing. That is, if you play a song or if a song can be heard (even in the background) when the app is running, then it will tell you the title of the song, and the name of the performer.
Audiggle can do much more than that, actually – it can provide you with extensive information on the artist in question, ranging from his biography and video clips to upcoming tour dates. Of course, the lyrics to the song that motivated the search to begin with will be displayed in all their glory for you to check them out.
