The standard motivational songs notwithstanding, my current favorite is "Break Free" by
Shirley Levi. The whole album, but take a look at the lyrics for the title song --
"Hey you with your dreams, life is not what it seems, wake up! Stand up for what you believe! Your dreams are your wings, let them carry you, not bury you...beauty's trapped in your head, bring it out, let it shout!" - BREAK FREE
