URL Snooper/Audio Streams

Are there some "general guidelines" on what to look for (say using URL Snooper)in terms of file type in determining if you have a proper audio stream to add to Yourmuze database? Any suggestions out there?

None that I can see. If you are lucky, the stream might have the word "streaming" or "live" in it, but there is no need for it to.
A tell-tale sign is that the media stream shows greatest data transfer. :-)
