I personally really like this song, "You Give a little Love" by Bugsy Malone, it reminds me of the movie "Pay it Forward". Basically it just says that you do a kind deed for another person and they do a kind deed for another,and so on, causing a whole chain and ripple effect of kindness. This Coca Cola commercial is using to show that if you drink a bottle of coke, which is so good and makes you happy, your world will be changed from rushing and rudeness to a light and fun day full of kindness which will be passed on and eventually come back to you. By drinking this beverage you could change the world.
