Zis iz very, very bad. Mon friend showed zis to moi tonight and I am very displeased with monsieur Koji Kondo.
Ze song he ripped off from iz called "Cry Baby" by Quincy Jones off of ze album "Mellow Madness" in 1975. Here iz a zip of a clip from zis song, and a clip from ze Super Mario Bros 3 song slowed down to ze same tempo as zis song.
Keep in mind zat ze key for both songz are exactly ze same. Ze notez aren't all exactly ze same, but it'z close enough for moi. Apparently Quincy Jones waz very popular in Japan, which makez it very probable for it to be ripped off by greedy Japanese composerz.
Ze source for finding zis I do not know. I believe mon friend found zis on another forum. If he getz angry about credibilitiez, I'll put hiz name on here.
Je suis choqué.....
