It is obvious when you notice it. These comments aren't too big of a deal by them self, but if you're a first time participant and have to sit on a "nice music", when there isn't any sound, for a few days until someone who actually played your game comes allong and cares enough to write a detailed comment, I would imagine that would be frustrating and leave a bad aftertaste. It's not Ludumdare, where you get 5 ratings in the first hours, it might take three days before someone even writes a comment.
