The music option contained in the game allows the player to listen to the songs in the game, as well as the original Game Boy Advance versions of the Superstar Saga tracks, by collecting tapes from all across the Beanbean Kingdom. It can be accessed from the in-game menu screen via Records at anytime during their adventure after it is unlocked. As in Mario & Luigi: Paper Jam, the music can be played through headphones even with the system closed.
