It's not daily I get excited about terrestrial radio, much less a latecomer to the Internet.  But, today is that day.  I just learned LA's own KROQ- the #1 Rock Station in the US is now broadcasting for free on the Internet in Windows Media.  It's a very solid 96kbps stream offering great fidelity and in-line purchase and the like.
