Cover art for Yellow Light lyrics by Of Monsters And Men

I like the previous comment, especially because mine is a little on the morbid side. ^^; I heard this after I heard Little Talks, so, I interpreted this to be a follow up, and that the female singer has just passed on, and the male singer, who was her husband in Little Talks, has come to guide her home.

Of course, it may not be a follow up at all, and is simply that the first signer has passed and the second singer is merely her guide, leading her from the dark and to safety/heaven with a yellow light, showing her that it's not all that bad along the way.
