Fans love to theorize about their favorite artists’ music, searching for hidden meanings or carefully concealed easter eggs. Usually, these sorts of hypotheses end up being just a bit of speculative though inaccurate fun, but one Reddit sleuth recently nailed his theory about Fleet Foxes’ new album, Crack-Up.

User blackbirdpie has apparently been bugged for years that the final song on Fleet Foxes’ 2011 album, Helplessness Blues, ended too soon. “I’ve always had the feeling that the end of ‘Grown Ocean’ seems slightly incomplete and was wondering if this was on purpose,” they wrote on the Fleet Foxes subreddit. They went on to say they felt like “a final chord or line is missing that would tie things up. It got me thinking that maybe Crack-Up will open with that missing chord, so that Helplessness Blues blends seamlessly into it.” They even figured out that an F chord would bridge the gap nicely, and recorded a demo to prove it.
