Interesting trivia, but not too relevant to today's gamers until a few months ago, when Powet.tv compiled a video of the song's known occurrences and put out the call to gamers everywhere to track it down in other games. Within a month, video confirmation for instances in Pikmin 2 and Wario Land for the Virtual Boy had been obtained, and earlier this week Powet posted a video of the song in Luigi's Mansion.
MobyGames lists 24 games Totaka has worked on, including the recently released Wii Sports, and it's a decent bet that his song is buried somewhere in most if not all of them. And so the call goes out to Nintendo fans across the land.
