I go to football to watch football, not listen to music, always have.
It's one thing having a few announcements over the PA system with a bit of background music before the game, but I can't stand loud music at half time. There's no need for it.
But what I really hate is when clubs play music (usually some cheesy crap too) after a goal is scored. Equally hated is the ridiculously loud music played at Wembley immediately after the game has finished. When your team has just won a cup at Wembley you don't need some knobhead blasting out his idea of an anthem when all you want to do is cheer your team!
These idiots are ruining the game.
