How it opens seems to depend on luck. The first time I tried it, I got there OK (from Joe Offer's instructions in the other thread) and it opened but of course it was a WMA, not the MP3 advertised and my Linux box isn't set up to play them...

Got in after a struggle on laptop but couldn't open it again - kept telling me something else was downloading and I needed premium service. Went back onto Linux and it told me I had to wait 8 seconds...

Anyway as a temp measure, it is at http://www.folkinfo.org/unknown.wma
