I sometimes need to play music at my work place to keep myself from falling asleep. I have subscribed to napster ($9.99 per month) for quite a while until I found this free online radio player. It’s call Pandora. If you are like me, listening to the same genre of songs, then you will like this. Basically, you start with typing in an artist’s name, or a song’s name, Pandora will search for a closest match. From this closest song, then comes the next related song, then the next related song, and so forth. The best yet, there is no advertisement! Try it out!
