The only actual song in the game is the one heard during Dribble & Spitz's stage, "Tomorrow Hill." It's... okay. The rest of the music is pretty darned awesome, between microgames and all. There's even a remix of the music from Balloon Fight, heard during the 3-D rendition of Balloon Trip from the original game.
BUT, the Mona Pizza song appears in the second level of one of Young Cricket's games. Everyone loves the Mona Pizza song.
