Here it is:

Traceback (most recent call last):
  File "./vimp3_player.py", line 112, in <module>
    Player().main()
  File "./vimp3_player.py", line 35, in main
    self.listen()
  File "./vimp3_player.py", line 41, in listen
    s.bind((HOST, PORT))
  File "<string>", line 1, in bind
socket.error: [Errno 98] Address already in use
