Stephan,
In the official crash report, nothing was said about pilots listening to the match. The pilots, after realising the mistake, tried to tune several radio broadcasts using the ADF in an attempt to find their position. In Brazil radio stations had to say their names and location every 30 minutes, it was a regulation intended to help pilots in remote areas. One of the flight attendants opened the cockpit door and the passengers heard the match. That's why some people say the pilots got lost because they were listening to the soccer match.
The pilots were very unlucky. The Chilean goalkeeper had simulated an injury and the Chile national team decided to leave the field. All the radio dudes got too excited about it and forgot to broadcast their names and locations.
