TNH Loopback works fine from webpages for the same stations you find in itunes. It may actually be double-streaming, but all you do is go to shoutcast, choose what you want, drag the listen link into streamripper on the web page folder and click the start button. Once that's on you can click the relay button, which may or may not be double-streaming, but yes you can listen and rip. In Panther with iTunes 4.7.1
(Version 1.0.5)
