Why does the station sound choppy or breaks up?
You may be in an area that has slower internet than required. For the streams to work well (without buffering constantly) you want to be in a high-speed (3G, EDGE, or WiFi) area. If you are in an area that does not accommodate a high-speed transfer, think of being on dial up, not very fast. Not to worry though! Most areas are high-speed now. Also, you can check out the userguides of each application for added troubleshooting tips.
