Oh, comon', guys. The trumpet rules. How can you not love the trumpet? Sure, the video quality blows, the announcers suck, there's rarely ever a scoreboard or gameclock (and when they do display one, it makes you think you're watching TV from 1972).
But I've set a clip of the William Tell Overture to be my signal alarm on FootieFox, my Hattrick apps, etc.
