The song Lifeline by Justin Jesso is about a person who is lost and confused after a break-up. The speaker feels like they are floating in an ocean and they need a lifeline to hold onto. They are struggling to move on, trying to convince themselves that they are comfortable sleeping alone, but the truth is they feel alone and incomplete. The speaker regrets the things they said during the break-up and wonders if there is someone else in their ex-partner's bed. They plead for a chance to start over and fix their broken hearts. They cannot stop thinking about their ex-partner and would rather be wrong than regret not trying to fix the relationship. The repeated phrase "Can you throw me a lifeline baby?" is a cry for help and a plea for their ex-partner to give them something to hold onto. The song's message is about the power of love and how it can be a lifeline for anyone going through a difficult time.
