A friend turned me on to this, and I in turn spread the love.
Pandora! Pretty cool idea for internet radio. Put in a song or artist you like, and using all kinds of space age ... space shit, it makes a radio station for you. Then when a song comes on, if u like it or not, u let it know, and it tailors it further. Can't rewind or repeat, but still pretty awesome. And for whatever reason, they haven't blocked it at work yet for me, so I gots me internet radio!
