Here is a GrooveWalrus playlist that I’ve put together in the last few days. It works with the latest version (3.4.2) and probably with some earlier and later versions. You need the GrooveWalrus application to play this playlist. It is in XML format.

You can add the playlist to your GrooveWalrus application through File->Open… file dialog. As a side note, GrooveWalrus also allows you to open m3u files this way.
