Burn It to the Ground - Nickelback.
So far, I've listened to this song for about eight times today. Couple of years ago, this used to be the opening theme of one of my favorite wrestling shows. A lot of people didn't like it, but I absolutely loved it. This song was very energetic, and it always got your heart pumping. In my opinion, this song fit the show quite perfectly. It kind of sucks that they had to change it, though. ):
