question about wp-scrobbler

The plugin works like a charm – but when I don’t have any recently played tracks, the “currently listening to” box/header (for lack of a better word) sits right on top of the next box. Obviously, I would love for it to display a small text like “no recently played tracks” in such a case, but I’ve no idea how to go about this. I emailed the plugin author, but didn’t get a response so far. I looked through the wp-scrobbler.php file, but didn’t see any place where I could put such a text.
Any help would be greatly appreciated 🙂
