The one I was refering to is called “Batch Art Finder 4.0” and you can download it from:

It can be fully automated or you can pick and choose - depending how brave you feel.
If you feel brave and trust it, you can simply select update all after it is done finding album artwork, or you can pick and choose the ones you want. But to answer your question, yes it can be fully automated. You let it run and when done, say update all.
Make sure to look at the options for this script to make the album artwork part of the tag inside the mp3 song. Also, make sure you pick “Google” for the artwork as it finds a ton more.
I wish Jaikoz did but it currently does not. Album art work is the weak part of Jaikoz in my opinion.
Maybe we can ask Paul to add it to the next release since the free version listed above works better.
