'Reco'gnize what is playing on a streaming audio
'reco' establishes a TCP connection with the server and sends an HTTP request string. The server (hopefully) responds with some header information describing the streaming audio channel, some audio data and then the name of the song being played (usually in that order). Some stations like WCPE [http://wcpe.org], while giving excellent broadcasts do not support title streaming over MP3 or Ogg. Using this software on such stations will only result in general station information and not the artist name or title of the track being played.
