creates a text file in .lrc format from current midi or mp3 song.
The file name is used from the original song file name and file extension is replaced by .lrc
If a file with this name is already existing in the song folder then a temporary file is created.
The text file is opened by notepad text editor.
GNMIDI and other players search .lrc lyrics in same folder with the same song name (e.g. use golden.lrc for golden.mp3 if existing) if no other lyrics are found inside the song file.
