Not a hard song to get really. First off I must compliment on the creativity of the song: using serious lyrics with a happy melody. I think I can speak for most people when I say the songs about "Has your life ever been shit? well so has mine, but Im doing something about it." He is relating to everyone and reminding them that "Each breath that you take has a thunderous sound" meaning everything you do in life can change the world even the slightest breath. And he simply tells you "Just sit back and hold on, but hold on tight
Prepare for the best and the fastest ride" Take life easy but don't slip up and life is fast and nastolgic.
