Shoutcast stations: If you have broadband, go for the ones with higher Bitrates. Play them on Winamp, if you don't have it, get it from here.
HUM FM is a radio station in Dubai I guess. They have some good DJs during their daytimes. One thing I disliked is that they broadcast their prayers when it is time for them, which I found annoying.
Raaga is another "okay" station. Their streams are mono?
AM-530 is a multi-lingual radio station some where in Canada. Stable Mono streams.
Radio Netscape needs you to download their player, the sound quality is pretty good. They let you listen only for a few hours if you do not have AOL.
Smashits is pretty good too. The sound quality is better.
