Simple things that every college band should do:
Put on a killer halftime show. This goes without saying...
Play down cheers (1st, 2nd, and 3rd) along with something for major defensive stops. Down Cheers -- and nothing else -- should be played on offense.
Play at the quarters, preferably a school song of some sort before the 4th. (And please, no hokey-pokey)
Play during timeouts and possibly during elongated stoppages of action.
On defense, have the drumline play. Encourage the student section to dance or do cheers along with the drumline.
Play the fight song (or other school song) as often as possible to pump up the crowd and the team -- only during timeouts or other stoppages of action though.
Play the fight song when your team scores -- and win or lose, support your team to the (bitter) end.
I know I'm leaving some things out, but this is really all you need. As fans, we need to support our band and encourage them to continue to support the university and its athletic teams at all events. We may not like everything that they play, but in the end we can't always get what we want...
I think that we need to find something else to complain about.
