I think "Welcome to the Jungle" by GNR would be better than thunderstruck. The intro to Welcome comes off kind of like a siren, so it would be a good fade from the siren into the song, and then about 30-40 seconds into the song, it crescendos, and busts into the main part of the song. Imagining the team taking the field at that moment gives me goose bumps. August 31st cant come soon enough!
