Internet radio station Pandora grows quietly
Commentary: Founder's long, tortured journey may finally pay off

As for myself, I'm still loving Pandora.com which I'm listening to via PandoraJam.

You can tear out the radio player in my Durango -- I just don't listen to local radio anymore at all, with the exception of NPR on my drive home to catch the news headlines. Between the several podcasts I listen to, and the playlists PandoraJam has created in iTunes, I have my own audible driving listening covered. In fact, I don't desire a satellite radio anymore the way I did for a while. The music I'm getting through Pandora -- via stations I have configured to match my tastes -- is better than the preprogrammed stations on Sirius or XM.
