ios - LiveStream: NSURL not working -

i trying test out live streaming application nothing working. tried using links people used on youtube , still nothing. here code.

-(ibaction)livestream:(id)sender {     nsstring *stream = @"http://www.surfmusic.de/radio-station/techno4ever-dsl,8457.html";     nsurl *url = [nsurl urlwithstring:stream];     nsurlrequest *request = [nsurlrequest requestwithurl:url];     [music loadrequest:request]; } 

this active station, listening right now. when loads on simulator says 'error' beside play button.

am doing wrong or link supposed special?
