You would just use
-Lyrics with that file. Don't assume that whatever other programs use for a tag is what exiftool will return. That's why I pointed you to FAQ #3. The command there would have shown you that the tag was simply
Lyrics.
Normally, on the command line, you would just redirect the output of exiftool into a file. For example
exiftool -Lyrics "Like a Cat.mp3" >Lyrics.txtThis may not work though because you're calling it from another program. In that case you can do something like
exiftool -Lyrics -w %f.txt "Like a Cat.mp3"which will create a text file with the exiftool output and the same base name as the mp3, i.e.
-w %f.txt "Like a Cat.mp3" will create "Like a Cat.txt"
Based upon the contents of your example file, you may run into Windows character code problems where some of the multi-byte characters get
Mojibaked. Hopefully that won't happen when writing the output to a text file, but other see
FAQ #18.
This output will still have
Lyrics : before the contents of the tag, but you can remove that with the
-s3 (-short3) option.
