Soothing
Actually a 9.5
I don't see how this could be much better, except maybe climbing to some final level of perfectly harmonizing tunes, with a bit harder beats and climactic melody.
I didn't feel a defining climax in this song, but not all needs one. Rather, this was a wave-pattern of soft moods, gently rising and falling. And very well put together; not at all boring but quite soothing, in a good way. Great work!
