"Bigger Than Me" contains a gigantic, emotional chorus and was the first song Tomlinson recorded for his Faith In the Future album. He felt it reflected his live show, so Tomlinson released it as the lead single on September 2, 2022. "It's definitely the biggest sounding song I've got on the record, definitely the song that stands out as being one that should be a single," he told Euphoria. "I wasn't certain I was going to have one of these songs on this record that has a big chorus. It shows off my vocals, so I'm really proud of what we got out of it."
