[keabro]

The metadata from title argument changes file name, but does not add meta data to file. --add-metadata only adds the title as metadata.

--metadata-from-title is not supposed to embed metadata, it's --add-metadata's task.
As seen from your log artist metafield is passed when embedding metadata:

-metadata 'artist=Illenium ft. Liam O'"'"'Donnell'

Here is why metadata is not embedded.
