Drag cover art from mashTape into metedata

Hi,

an idea for a future feature: say you have a song which does not contain the cover art in the metadata. Say you play it. Automatically (most probably) mashTape will show while playing the cover art in the discography. Why not add the possibility to drag the cover art shown in the mashTape window into the metedata information and save it as part of the file?

I think it would be a very useful feature.
