Cool Program for music lovers

I found a great product for music lovers.  Pandora is a web based program that you can create radio stations of the music you like.  If you are a Jack Johnson fan, just key in the artist or the songs name and this program will create a radio stations of like artists and songs and stream them to your computer.  I have a tab set up in firefox so everytime I cut on my browser, cool music starts playing.  You can even purchase a squeezebox and have the music broadcast over your stereo.  I love it!
