Babylon

i think this song is reflecting on an argument with a loved one. he starts with friday night after the argument everything changing green to red, thinking of the situatoions in his head and how he was jealous and bitter. in the second verse he starts to realise that he is wrong, things are changing red to green, he's thinking of how he can make it up to her "chemicals running thru my bloodstream" and "only wish that you were here to show you how i really feel, admit to some of those bad mistakes ive made". by the third verse hes thinking how hes made such a mistake after he goes to see her and shes not there, but as he returns home, to his surprise, shes waiting for him. the days dont actually represent days, i just think they represent the stages of feelings a person passes thru in such an instance. the chorus is stressing that the loved one should understand that their love was never in doubt, so let go of your heart and head and embrace the fact that i love you so much and im sorry.
