Most horrible sounding thing ever, or one of. Really annoying. I didn't catch the Confederations Cup so wasn't aware about the problem that was discussed about the sound then. But having listened to it once, I understand why people are annoyed. It serve no bloody purpose other than to annoy people. With gendang and what not, at least there's a rhythm or something. But this just like 'buzzz'... whole game long. WTF!
