I'm a fan of Rage as the choice. FOB is a terrible band in my opinion but the song does kinda work as a goal song. The idea of Fall out Boy as a Flames song kinda kills me inside a little, you know the same way the Duck Sauce - Barbara Streisand song did.
Failing the RATM song, I think something more "anthem-like" that could be chanted by the crowd would be a good choice.
An example would be "Righteous Smoke" by Monster Truck. Perhaps some editing would be good putting the lyrics before the chant.
