For me, this song means that everything is so wonderfull, & there is no reason to be sad. When he says that he will blend up the rainbow above you he means he will cheer the person up! Probably she feels sad becuase of events, depression, and just life. He is just telling that, in spite of everything going on around us. There are in fact millions of reasons to smile :). This song makes me happy instantly. Sometimes we all feel down, we all feel that we failed, or that we did everything wrong. We have a hard time figuring out what life is, especially love, and when we fall we feel devastated. This song just tells you, its ok to fall, its part of life, you learn from it, become a better person and embrace the beauty of life. As long as you breath you can stand up and try again! :) so just smile (: because as hard and depressing as life can be, on the other side it can be wonderful thrilling and the best experience ever! You decide!: D
