Installed Streamripper, as a learning experience-great article. Using the example IP and port numbers, everything worked fine.
When I control-click on a "Tune-In" link on shoutcast I got:
No IP or port number.
Also, I guess I just don't get something. If you have to know the IP address in advance, isn't this a lot of work, as well as being nonspecific. ie. you can get a stream, but what you get is sort of random, no specific songs.
I must be missing some basic concept.
