When comparing the graphics and music between Adventure Island and Wonder Boy remember that they came on two different systems with different hardware capabilities. Generally speaking, the NES had a better sound chip than the Master System (except for some of the Japanese Master Systems which had an upgraded sound chip), and the Master System had better graphical capabilities than the NES. This should help to explain why Wonder Boy had seemingly better graphics, but was worse sounding.
I haven't had a chance to play this game yet, but it is certainly on my "to play" list...given that you gave it such a high score, I can't wait!
