I'm not exactly the "Music aficionado" but In my opinion, I thought Kirby piece was a bit to "Jumbled" for a lack of a better word, all the instruments sounded to alike in tone so it sounded more like someone was dragging there hands across a keyboard while someone else was playing an actual song in the background. Also the individual volume of each instrument could probably be adjusted so that the "Main" Melody is in the foreground, rather than mixed with the rest of it.
