10 months ago Nevermind. I figured out how to do it and now I'm embarrassed.
To anyone who's reading this and doesn't get it. You want a URL to the cover art at the ready (use Google Image/DDG Image). Paste the URL into the "Search Box" under Custom and it will generate it. Then fill in the metadata.
According to the FAQ, items that are not in the databases with cover art (including stuff struck down suck as the King Crimson discography) will not appear in the search to drag-and-drop.
Seeing as there is the option to add custom items, it would be nice to add custom images to these items. Otherwise there's just a question mark on the chart.
