Brandyn commented on the song’s background during an interview with Starry Constellation Magazine:

“Lost” was written almost a year ago for a couple of my fans who lost a friend in school. They were so young when it happened and I was one of the only people there to help them through it. I felt burdened to write it.

Again, it was one of those moments where I felt as if I’m a vessel for something greater. Once I write it, I told them about it, but never released it. I knew it had to be released in the purest form so that it can at least be discovered by people when they need it.

Some songs are just urgent and their purpose is for the people that can’t wait to hear it. In this case, I felt like a year was long enough. “Lost” was one of the factors driving me to put out a full project.
