At last I see a streaming solution I really like.
Pandora plays the music I choosed to listen. I am not dependent on the DJ mood, don't have to switch channels when hear the commercial and may skip the track I don't like.
I gave a name of a band I wanted to listen and it made a playlist of the similar music - so I don't choose each song, and still listen what I want.
If you got a broadband connection - try it. Good implementation of Web 2.0
