I feel ya there. Those two songs would be perfect, and I'm sure they're not widely used for intro music.
I can't wait until Iowa State finally lands on an pre-game routine and intro and sticks with it. That said, they have to get it right first, as was the case with the uniforms. Pre-game is such a cluster f- right now that it's hard to build any momentum and excitement for the average Joe in the stands.
They can start by limiting Jeff Johnson's pregame routine to a greeting followed by the Cyclone - Power cheer. Then get off the field and let the fans carry that until the team is about to come out.
