The first time it came on during play, it seemed like it was just a mistake. But then it happened after the ball went out for a goal kick and didn't stop when the ball was put back into play. And again. And again.
Exact same thing happened in Christchurch. I really hope that this isn't a directive from the club, because they should be saying the exact opposite (i.e. no music from the first whistle of the half until the last whistle).
The pre-match music drowned out the chanting from the Zone as well, surely the chanting etc is one of the drawcards of football, and if people wanted to listen to music they would go and watch rugby or a T20 borefest.
