Pandora Radio. If you are not using this free web service (Web 2.0 tool!), then you are missing out! I love it.
You can type in a favorite artist or song and Pandora searches around and finds other songs/artists that are similar and plays them for you one after the other…no commercials!
Start a new tab on your desktop and you can listen all day without interruption. Occasionally you have to let it know that you are still listening.
Try it out – Pandora Radio
How to start a new tab: PC users – hold the control key down and press “T”
Mac users – hold the apple key down and press “T”
