I have %lyrics% and album art tagged on my FLAC and MP3 files. For the purpose of an export, I'd like to include a column that simply shows whether the file either has or doesn't have lyrics or album art.
For album art, there is the tag %_covers% which outputs the number of covers. But for lyrics, I would have to define a new one and set it based on the presence of %lyrics%. What logic do I use for that particular action?
