Cody Simpson - La Da Dee Lyrics Meaning

'There's no way to sing this song about someone else everytime ur not with me i start to lose my self' It means the song is singing is not meant for anyone else except her, usually when we're not with the one u love u start to feel empty thats what simpson is talking about. 'La da dee da da de do la da dee me la da de you its only me its only' meaning when you are look at her all u thin about is only her and u thats what cody simpson was trying to emphasize.
