Albumart.org doesn't like it if you send a query that contains parenthesis. For example: "Devo-Recombo_DNA_(disc_1_of_2_-_Sequence_A)" won't yield any results. Abcde names directories like this for multi-disc packages. An apparently decent way around this is to lop off the string submitted to albumart at the first paren encountered. Another enhancement is to refrain from writing a cover.jpg file when it didn't find a cover image. Here's a sloppy diff-ish thing of what I'm talking about

albumpath="$1"
+title=`echo $albumpath | cut -d'(' -f1`
...
-encoded="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$albumpath")"
+encoded="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$title")"
...
-echo "Searching for: [$1]"
+echo "Searching for: [$title]"
...
+if [ -z $coverurl ] ; then
+ echo "Unable to find cover art for $title."
+ exit
+fi
