One More Light isn't about saving yourself on your own, however. It's about realizing you're not alone, no matter who you are. That idea is expressed clearly in 'Heavy,' the duet between Bennington and Kiiara having a key meaning for the record. Bennington sings with a somber tone as the dark synth chords introduce the song, his drug and alcohol abuse giving the chorus lines "I keep dragging around what's bringing me down / If I just let go, I'd be set free / Holding on / Why is everything so heavy" a very strong reality. Kiiara joins the song, her inclusion making the point that anyone, regardless of age of sex, can face the same problems. As the two come together in the explosive bridge, they reach the realization that they never had to fight alone; they always had each other, two people who knew the other's pain, to come to. As the song explodes with a powerful, guitar-driven emotional climax, their newly realized bond serves as the key to their healing.

A similar idea is channeled in 'Halfway Right,' where Bennington's dreamy melodies serve as a message to his younger self, warning him about the tough times ahead. He explains it as a battle he can never win on his own but there's no one left to fight with him, the chorus chanting: "I scream at myself when there's nobody else to fight / I don't lose, I don't win, if I'm wrong, then I'm halfway right." Chester also reflects on his past in closing track 'Sharp Edges,' the folk pop track where he wishes he had heeded his parents' advice, the chorus chanting "Never listened when she said sharp edges have consequences, I guess that I had to find out for myself / Sharp edges have consequences, now / Every scar is a story I can tell" with a groovy melody to back it. While it doesn't have defining concluding quality to it, 'Sharp Edges' reminds us to remember the foundations of what we know, and the people who love us will always have the answers to heal us.

Not all of the struggles are our own, though. That's where 'Talking To Myself' comes in. It's synth-lead in is accentuated by alternative guitars and a funky bassline, giving it a very energetic sound, and even though its message isn't as upbeat, it really fits together nicely. The song comes from the perspective of Chester's wife, the pain she felt while watching Chester suffer through his darkest times while she watched on, powerless being the subject of the track. The same feeling of helplessness is the subject of the pop rock ballad 'Battle Symphony,' but instead of talking about being helpless, it reminds you that even when all seems loss, people are there for you. The chorus chants, "I hear my battle symphony / All the world in front of me / If my armor breaks / I’ll fuse it back together," the voices of all those who back him being the armor that protects him from hitting rock bottom. He begs, "Please just don’t give up on me," before he truly feels the love, ending the chorus with the confident outcry, "And my eyes are wide awake." Energy like this is channeled in 'Good Goodbye,' where, with the help of Pusha T and Stormzy, the band builds upon a sense of trying to be put down when they are at the top of their game.

Not all songs are about each other, and not all songs are about healing our own problems. Others are about helping us heal others, such as the powerful track 'Invisible.' Mike Shinoda takes the lead here, the synth-led intro going straight into his sweet melody. The track is directed to his kids, as he apologizes for all the future fights they will have and for always being gone. For any parent, it's only natural that there will be disagreements with their children, and Shinoda puts all of those struggles to the perfect words in the pre-chorus: "I was not mad at you / I was not trying to tear you down / The words that I could've used / I was too scared to say out loud." Through all the disagreements they may have, at the end of it all, Shinoda will be there for them to the very end: "If I cannot break your fall / I'll pick you up right off the ground / If you felt invisible, I won't let you feel that now."
