Fast, simple, free, effective.

The only way it could be improved is if it did what PearLyrics (the .app) did but with artwork. That is to say that PearLyrics has an auto-mode for the app that lets you let it run and fetch all the lyrics for all of your songs without any user intervention. This would be a big leap for artwork...no app currently does this for art. For auto-mode to be efficient, it would need to be smart enough to fetch artwork and populate the album so that it doesn't download artwork for each song.

Regardless, this, as a widget, is best in class.
