That works very infrequently. Most radio stations are moving to Flash based players to be able to control where the stream is played, so they can in turn force ads on the listeners. This leaves listeners that want to go mobile, in a bind, since the MMS or RTMP address for the stream is hidden in the player, and the player won't play on a BlackBerry since there is no Flash support.
Even then, this doesn't get the music to the car stereo which is what the OP is looking for.
It's more complicated than "just stream".
