Maybe everybody already knows how to do this, but I thought this might be of interest to this forum:

You frequently might want to download a streaming mix from a website for a variety of reasons like poor bandwidth or portability, but the interface on the site doesn't provide a link for doing so. Actually, all you have to do to essentially download any streaming file is first find the name and server address of the streaming file, then use an appropriate download manager to download the file from the server.

If you want to waste some time, you can write some packet sniffing scripts to do this yourself, but since you probably have better things to do, you can just use a commercial application like URL Helper (http://www.urlhelper.com/). With this or similar software, for example, you can easily download any of the streaming archived mixes from samurai.fm or other such sites.
