• This ethereal number finds Biffy Clyro vocalist Simon Neil singing of forgiveness and trying to learn. "It's about not being afraid to make mistakes in life, because that's what life is," he told Apple Music. "Unless people have done something truly heinous, I think they deserve second chances."
• Biffy Clyro recorded the electronic number for The Myth of the Happily Ever After at their home studio on an Ayrshire farm. The rock trio originally planned to drop a record featuring some tracks that didn't make it onto their previous album, A Celebration of Endings, but when COVID-19 stopped their touring plans, Neil wrote some new songs for the album. "Existed" came really fast. "Literally in one day," said Neil. "I just felt magic in it."
• "Existed" was the song that made Neil realize something new was coming out of him and they had an album on their hands. "That was actually the key song that made us decide that this was a record," he told Kerrang. "I'd been messing around with that on piano for a couple of weeks, and it was very fresh. I played it to the boys one day, like, 'What do you think?' And they went, 'Yeah, it's good… Should we do an album, then?'"
