One song that defines the band. Well, at this point in their career I would say the song that defines the band is It's My Life. The song is about living how you want to live and doing things your way without comprmising their ideals and that seems to be the credo the band follow at this point. They write and record what they want and tour where and when they want. They don't really seem to adhere to anyone else's guidelines or rules. Lost Hightway is a perfect example of that IMO.
