Pandora Box

Do you know Pandora project? Is was created by the Music Genome Project and consists of a webpage with a java applet, to let you hear music. You choose one (or more artists) and Pandora plays music from those artists, and other it thinks are similar. Then, you can say you like or not them, letting the software adjust to you.

I just wonder... will I use more than my 2GB international traffic for this month?
