pandora.com is an awesome service…
this open source app >> Pandora’s Jar allows users to time-shift songs… some would call it a Pandora Ripper… as it does allow you to save the MP3, tag it using Last.fm and listen to it at a later time. it’s like a DVR (you know Tivo for Television?) except it’s for audio… so i guess it’s a DAR (Digital Audio Recorder) specifically for Pandora.com’s broadcasts.

just thought i’d point it out.
