Last FM's excellent playlist streaming widget

I have been on LastFm for quite a while, but I've just discovered their streaming playlist facility. I have whacked it onto my sidebar, half way down. It's also below this posting. Basically, you just click on the large arrow and you can hear my playlist of 30-ish current fave tunes. It's very clever. To put your own version on your blog (with your own choice of music, of course, you just click on "Get your own" at the bottom of the box.
