After you've beaten a boss for a given section of the island, head back to the Extras Menu. You'll have unlocked a bonus music gallery that features the tracks played in the levels of that particular section. It's also worth noting that you must defeat the boss yourself; if you use Super Kong to get past the fight, you won't unlock the music.
