I use this code to get album artwork when Beets fails

encoded="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$albumpath")"
url="http://www.albumart.org/index.php?skey=$encoded&itempage=1&newsearch=1&searchindex=Music" 
coverurl=`wget -qO - "$url" | grep -m 1 -o 'http://ecx\.images-amazon\.com\/images\/I\/*/[\%0-9a-zA-Z.,-]*\.jpg'`

It basically searches AlbumArt.org and scrapes the first result.
