It's very difficult to review a recording based solely on a music video track or a live performance, for the simple reason that it's not the original recording. These things differ from critic to critic, and it's more of a personal stand than it is a universally-accepted standard, because there are instances where the visual delivery is just as important as the auditory aspects (e.g., 2NE1, Big Bang). But my stand is perfectly highlighted in songs like "ALL MY LOVE IS FOR YOU"
There are two things that a fragile melody like this needs -- the first is kick to give it some conviction, and the second is depth to make it less sharp on the ears, and to support the fragile melody. And I think it's safe to say that the arrangement literally pulled it together and delivered.
The piano line isn't extremely obvious because the mix favored the vocals over it, but it's understated in it's beauty, and it gives the song that subtle kick. The strings are similar because they do take as much center stage as they can, giving it a much needed kick, but unlike other string sections, this one is simple to start with. It's structured more like a drone or a bass line than it is an actual melody, so it really has no reason to hit you over the head. Which is perfect.
So where does the other half of the depth come from? From the production, which is gorgeous without being generic. It's neither overproduced, nor is it underproduced -- it's just right. The way everything was put together, the way each element sounds in relation to the other, literally makes the song glow. There's no other way to describe this song, really, because it really does glow. Hearing it not only puts a smile on your face, it goes that extra mile and makes you all nice a fuzzy inside.
I love a pretty song when I hear one, and I think a lot of you know that. "ALL MY LOVE IS FOR YOU" is probably as pretty as anyone can get. For now, at least.
