Note that there's 2 things to download an install, the actual player, and the shoutcast engine. I don't know if you can preload a shoutcast address, but what I use this for is to browse to shoutcast.com on my phone with the Web browser, pic a station and click "listen" or "play" or whatever. It will download the playlist file to your device, put it in the "Shoutcast" folder on your memory card, and then open the internet radio player.
