Hack of the day - Chopshop. Rips Shoutcast radio MP3 streams into separate MP3 files on your disk. It requires Twisted CVS (or 1.0.2 once released).

There are already existing programs that do this (Streamripper sounds nice, gotta steal that mp3 silence trick), but Chopshop is probably the shortest one - I wrote about 230 lines of code, half of it added to Twisted as generic Shoutcast protocol support.
