Keselowski's theme: 'Won't Back Down'

BRISTOL, Tenn. -- Brad Keselowski chose "Won't Back Down" by Tom Petty and The Heartbreakers as his song selection for driver introductions Sunday at Bristol Motor Speedway.

The song choice is a clear message from Keselowski, who has vowed not to change the aggressive driving style that has gotten him to NASCAR's top level but also angered several veterans. Sunday will be Keselowski's first Sprint Cup Series race since he was intentionally wrecked at Atlanta two weeks ago by Carl Edwards as payback for an earlier accident.

Edwards, meanwhile, selected "Black Betty" by Spiderbait for his song selection.

Bristol started the practice last summer of allowing drivers to pick their introductory music, and the idea was wildly popular for the participants and the fans. Many drivers have created opportunities over the past month for fans to vote on their song selection.
