I listen to internet radio at work. Low volume, fairly noisy office so fidelity is not a major concern (ie, mp3 quality acceptable). One of my favorite stations is WUMB (folk music) over live365com's player. If you go directly to WUMB's website (
http://www.wumb.org/) instead of starting at
www.live365com you will get all the music for free without the annoying live365 station breaks.
Live365 has lots and lots of stations, of all different variety. Sometimes they are blacked out except to pay users ($3 per month). Nonpay users get subjected to annoying station breaks, and the rare paid commercial, whenever you change stations or every ten minutes or so. There is something there for almost any taste-I like Biker Bar Live! and Into The Mystic.

I've just wandered into Yahoo's service,
http://www.launch.com. This seems to be a similar service to live365, with pay and non-pay versions. Both claim higher quality for pay users. Many more of launch's stations are blacked out to nonpay users. On the positive side, launch has a feature to rate the songs which will fine-tune your playlist, and no ads (at least so far) for nonpay users.
All of these appear to be legit and pay royalities to the artists.
Anyone have any other reccomendations?
