I found a pandora like Music site called SeeqPod Music. It’s easier than pandora. You just register then you have a simple interface. on the left there is a panel with scrolling song title. You may add songs to your play list on the right clicking on a green arrow. As soon as you add songs to your play list, SeeqPod starts playing them. For each song, SeeqPod suggest other songs that you should also like. And what is new compared to pandora, SeeqPod may also suggest video (via YouTube) when they are available. The interface is light simple to use and not too much Ajax powered.
