Regarding the tracks, when Mr. Miyamoto mailed me my copy of the game, his personal note said that they chose the tracklist on the following rough guidelines:
"RE: the tracklist.
- Axiom A: Whereas it is an international release with everyone receiving exactly the same songs, the tracks needs to cover a lot of ground and include differing regional flavors.
- Axiom B: Whereas the decision was made not to display a scores or guide by default while playing the songs, they need to be relatively simple and recognizable melodies. Addendum: Combining this with Axiom A, it is clear that effort must be made to choose songs that are recognizable around the world, as much as possible.
- Axiom C: Being a game that attempts, first and foremost, to foster creativity with music, there need to be a good number of very simple tracks to get the player started, and on which the player will feel more comfortable experimenting.
- Axiom D: Whereas encouraging a more classical flavor of musical education is important to the game in its differentiation from other rhythm games on the market, some famous composers and pieces will be featured.
So, the consequence is that we numbered it down to the following sections of the tracklist:
- 1. Extremely simple and recognizable songs, pursuant to Ax. C.
- 2. Famous classical works, pursuant to Ax. D.
- 3. Folk tunes from around the world, including ones originating in the US, Britain, Germany, France, Italy, Japan, and more. See Ax. A.
- 4. Pop tunes, but only ones that made it into the top of the charts worldwide and that nearly anyone is likely to recognize (eg. Material Girl). See Ax. B, Addendum.
- 5. Nintendo tunes, which require no justification.
So, meeting all those requirements was tough, and the classic Nintendo tunes, while present, were not the only thing to factor in while producing the tracklist."
This is the word of Miyamoto for the people of Miyamoto.
