Often times someone does not realize what they have until its gone. Sometimes you don’t realize the true value of someone and all they bring until they are gone. This is what happened to singer songwriter Passenger and he wrote about it in hit Let her go in his album all the little lights. He wrote this song after a breakup and the lyrics are about him realizing how important this person was in his life and all the factors they brought to his life. He uses long metaphors and strong language to convey what he feels and tells it as a cautionary tale of beware of what you can lose. He starts out the song with the multidimensional lyrics

Well, you only need the light when it’s burning low
Only miss the sun when it starts to snow
Only know you love her when you let her go

The quote talks about how you don’t realize you need the light or the sun until its gone and one realizes all it did for you. The word burning is strong as it can show his love is still burning for the person, the candle light is low, and he feels like he is burning now that he feels empty. The multiple uses of the word conveys all the different emotions he feels as he is writing this and trying to convey them all in the song. He also uses metaphors to show what his love was like when he says

Only hate the road when you’re missing home
Only know you love her when you let her go

He comparing the feeling of being homesick when you miss your home to how he misses the person he loved. This also shows the anaphora in the song. The melody that is repeated multiple times starts with only. This repetitions shows all these different things come together to show how much he loves her and misses her.

Finally he uses imagery to convey his emotions to fully help the listener understand what it is like.

Staring at the ceiling in the dark
Same old empty feeling in your heart

The imagery of someone heartbroken in the dark after the light before mentioned went out feeling empty is well conveyed here. He is able to convey his strong emotions into the words and that is why this song is a form or poetry. Many different ways Passengers is able to convey the feeling he has and what he has realized after the person he loved is gone.
