Adults are fine, but there’s something about a child’s birthday party that always feels especially touching: the cake, the wonder, the reckoning of how exponentially they grow in such a short span of time. But this isn’t the bittersweetly reflective parent playlist, it’s the kids’ party one. So stretch out, warm up those vocal cords, and prepare to celebrate—because it only happens once a year. Our editors mix things up now and then, so if you hear something you like, add it to your library.
