Last.fm is a very cool internet radio. First, you do not have to register to listen to it. Second, if you do, it will track what kind of music you are listening to and will create personalised "radio station" for you. Third, you can share your tastes with your friends. (Well I am trying to do this last part with our blog anyway.) This week's song is A Dios Le Pido by Colombian superstar Juanes.
