Streamripper allows you to download streams using Winamp. I found this after visiting Shoutcast, a directory of radio stations you can listen using your browser or favorite media player. I started listening to some great hip-hop mixes on .977 Hitz and I wanted to record them to play them later. That is when I found Streamripper.

Streamripper’s description

With the emergence of file sharing protocols such as Napster, Gnutella, and now Mojonation and Freenet, the average Internet user can download nearly any mp3 he wants in a matter of no time, but many times people don’t know what they want. Streamripper allows you to download an entire station of music. Many of these mp3 radio stations only play certain genres, so you can now download an entire collection of goa/trance music, an entire collection of jazz, punk rock, whatever you want.
