The ending theme of Metroid II is one of my all-time favorite themes. Like Ham On Rye I have a save on my cart at the very end so I can go beat it to hear the end music; I used to press my game boy up against my ear to hear it better.
Let me say that this remix is very good. But, because of how much I love the original, I can't help but hold a very high standard for what a remix of it should be. So I have a criticism.
Basically I don't feel the remix was opened properly. Anthem spends 1'09 covering what was, in the original, an 0'08 lead in. That's not necessarily a problem, but for someone who's familiar with the original it builds up a lot of anticipation.
My problem with Anthem comes at 1'10, when the anticipation built up over the past minute just falls flat. In the original, after the opening bit the theme comes in immediately with a sort of energetic fanfare-ish sound. In the remix, however, there's this sort of winding-down noise, after which the theme fades in, becoming recognizable a few seconds later. I found it to be a big let down.
The bit from 4'19 to 4'25 shares the same problem, but not nearly as much, because the theme is picked up again that time.
Other than that the only complaint I can make is that at some points it felt like the melody was too soft relative to the beat.
Now, I'm not trying to say that that ruins the remix. That would be a gross overstatement. In fact, from 1'18 to 4'18 the remix is very, very good. But it took a long time to shake the feeling that something was missing.
