Nice work! Thank you for this tool!! 
I have some questions:
a ) How can I save the lyrics to a specific path (not the same where the mp3 are stored)?
Example:
I would like to store the lyrics for the 10cc-song '01 - The Wall Street Shuffle' in the path
D:\mp3\Lyrics\1\10cc (01 - The Wall Street Shuffle).txt
(First letter/number of the Band as directory name, no need for the source in the filename)
If this is too complex, I would just be happy with a fixed different lyrics path like:
D:\mp3\Lyrics\AllFoundLyrics\
b ) How can I run the lyrics.exe without the final result windows?
Just the logfile or nothing at all would be enough for me.
c ) How can I export only the files not alread including lyrics? The command in the PDF $filename(txt,utf-8)$loop(%_path%)%_path%|%artist%|%title%
$loopend()exports ALL files, not only the one without lyrics, right?
d) Is there any known limit of number of tracks to get the lyrics? Are the sources banning my IP if I use your tool to many times?
