Is there a way to add Album artwork to the metadata in Engine DJ?
Yes, you can use the “MP3tag” software to load the cover art into the MP3 file. Then with Engine DJ use the command “Reload information” and it will update its DB with the tags of the MP3, therefore also with the cover.
yes lots of third party software can add album artwork. I want to only use Engine DJ to edit metadata.
You can use Engine DJ to change the tags (Title, artist, album, etc), but for now it is not possible to add or change the covers. So if you want to add a cover you have to use another application.
