Justin bieber - believe.
This song is basicly telling believe in what you dream cause they will come true no matter what you just should know that one day one of us will be on tv do something other than voilence. All I do when somebody knocks you down get back up and what ever you was trying to do again an always know believe. That's what I always believe in know matter what happens I will always have god and my favor song to go back on believe in all your dreams they will come true.
