Bob Marley’s “Three Little Birds” may be the most often used Reggae song on the planet, but it’s also probably one of the most uplifting, heartening songs ever performed by anyone, period. It’s one of those songs that never fails to lift your spirits and put you in a good mood, no matter what kind of day you’re having.

I remember repeating the song over and over in my head whilst at the dentist, or on the way to see my father when he was in an induced coma at the hospital after his fall. It doesn’t happen every time, but often, when I need to calm down and just go with the flow, I listen to this song—or play it in my head—and indeed, it feels as if every little thing is going to be alright.

Then, of course, Will Smith had to sing it to himself in I Am Legend—which isn’t bad because it was Will singing it, of course, because he’s one of the sexiest actors alive, and there’s not anything sexier than a guy who looks that good and can sing. The problem, of course, is now that I’ve seen the movie and pretty much been scarred by life because of it (particularly due to the violent, weird ending, which is completely different from the more haunting, yet more meaningful ending in the book), I can’t hear the song without associating it with the film.

From the infected mother to the death of Smith’s character’s own daughter and wife, to the dead babies in the crib to the killing of so many infected people—I just can’t stand it. I think about the end of the world a lot these days—who doesn’t, so many things are so bleak—but I am comforted that it’s not just our generation; my mother tells me that when we were kids, she often thought about how she’d have to protect us from a Russian raid or atomic warfare. (To which, of course, I tell her, “You could pretty much just sit and die with us, Mom. I guess reading a few books to us while it happened would have helped.” Yeah, she doesn’t like that very much!) So it’s not a new fear, to say the least.

Then, more recently, I heard the song remade for children on the program Noggin (now known as Nick Jr.). It was paired with some of the sweetest cartoon footage you could ever hope to see, with baby animals with their mothers or fathers taking care of them in the rain or other precarious situations. Then I remembered that the song isn’t about zombies or the end of Earth—and I’m sure that Marley would hate that it was associated to those things, anyway—but about how everything, indeed, will be alright. And if we could all remember that right now, we’d probably all be much better off.
