"Ultimate Bowser" sounds like a mix of the previous Bowsers' theme and Bach's Toccata and Fugue in D minor."Goal & Score" sounds like "Put On a Happy Face" from Bye Bye Birdie.Probably the most bizarre example in the game is the intro theme, which is suspiciously similar to, wait for it.The series-standard athletic stages use a jazzy Benny Goodman-esque swing tune that's also quite reminiscent in places to "Mad About Me" from the New Hope soundtrack.The Castle theme is similar to "Song of Storms" from Ocarina Of Time, to the point that there is an annoying number of comments about it on almost any YouTube video of the piece.
