I like the idea of a thread for song suggestions too. Music must be hard at events like this with people of all ages and from all parts of the country and a few outside of the country. But it seems very important too. I almost think you need a professional at least at the in-season events who can sense the mood of the crowd and energize it when needed. Even songs I don't normally like, I enjoy at the right moment, such as the song playing in the background at the Boston final match
