I kinda dig on Time to play the game from Drowning Pool. .. that always seems fitting for football.
Though I would prefer to have it be something the band can play too. Maybe something like the final countdown by europe ... that could be done in an orchestra rock style.
Its all a matter of option.
For some fans, the andy grifith theme would be enough to get the blue hair standing on end. For others they might need more drowning pool, disturbed, or pantera to get motivated. I think it is time to not push fans away based on preferences of how they choose to support their team. There is room for both... there are 4 quarters.
1st quarter hard hitting rock, 2nd quarter some rap, 3rd quarter country, 4th qurter fill in the blank.
