Basically, I switched to using the album artwork and adjusted the formatting of the notification to suit my own taste.

Thanks again!

tell application “System Events” to if (application processes whose name is “iTunes”) is not {} then
tell application “iTunes”
if player state is playing then
set trk_arts to the artist of the current track
set trk_name to the name of the current track
set trk_albm to the album of the current track
set trk_num to the track number of the current track
set trk_desc to (trk_arts & ”
” & trk_albm)
if current stream title is not missing value then set trk_desc to current stream title as string
else
set trk_name to (”iTunes Status”)
set trk_desc to (”iTunes not playing.”)
end if
end tell
tell application “GrowlHelperApp”
set the allNotificationsList to ¬
{”Show Status”}
set the enabledNotificationsList to ¬
{”Show Status”}
register as application ¬
