The k4 and touch have a built-in audio player that you can call from a script or SSH command line. It does not have built-in streaming support, but it can read STDIN so you just need to pipe wget into it to play HTTP audio streams.
The audio continues to play over wifi even when the kindle is in screensaver mode, if the USB cable is plugged in to supply power (and the kindle is configured to keep wifi up like it does on the k3).
