Bieber's write-in campaign has been denied by the powers-that-be, and that's fine, Auburn. If you want to turn down the opportunity to have the most metal intro in all of college football so you can have one of eight songs everyone else uses, oh, sure: you go right ahead and serve up that cold hot dog on a stale bun, Auburn. Bieber will be waiting for the right moment, stalking you patiently like a praying mantis on Adderall with a sniper rifle. And when the time is right, he'll kill you, because Bieber's favorite dish is revenge, and he likes it served three tenths of a degree above absolute zero, bitch.
Run all you like, Gene Chizik. It will only make him angrier.
In the meantime, you have only once choice for an appropriate song for Auburn's intro: HAMSTER TRUCK.
