Quote by Marty McFly

"This is heavy."

"There's that word again, 'heavy.' Is there something wrong with the Earth's gravitational pull?"

"I'm your density. I mean, your destiny."

"You're my best friend, and I care about you, but don't ask me to do this."

"Music is the language of the soul."

"My music comes from my heart."

"Music transcends all language barriers."

"Music is the universal language of love."
