That could be the case too, but I have not played The Legend of Zelda: Spirit Tracks in a very long time, so I do not remember. Regardless that mechanic got a hint more difficult as the songs got more advanced.
You didn't ask, but I think the worst game for gimmicks is Spirit Tracks with the train, spirit flute, and touch controls. To be even more specific the spirit flute is my least favorite gimmick. The train and touch controls I don't dislike, but I prefer most of the other games' methods of travel...
