I have the "Untitled" icon as well but only when launching the webapp through its own launcher icon. But the webapp will also come up if it detects Grooveshark open in a tab, at least in Chromium. So I have Grooveshark as a pinned tab in my normal session instead of launching it separately.
I modified latest version posted by Alex Stefan Kaye to show a notification when a new track is played, it's attached.
