Cover art for Oxygen lyrics by Colbie Caillat

To me, this song is about a girl who is in love with a guy. She likes him a lot, and she's not sure how to tell him (hince the "how am i suppose to tell you how i feel"). She wants to be with him, and she's trying to tell him that'd they'd be good together. ("i will make you happy" thing)

Just my opinion :D
