The soundtrack for Pokémon Ruby/Sapphire is now available on iTunes for purchase. Titled Pokémon Ruby & Pokémon Sapphire: Super Music Collection, the OST is by composers Junichi Masuda, Gō Ichinose, and Morikazu Aoki.
Like the previous Pokémon music collections, it includes adapted and remastered versions of the tracks in Pokémon Ruby/Sapphire. The Pokémon Company says that the game’s composers took much of their inspiration from the Japanese island of Kyushu.
You can grab the soundtrack for $9.99 off of iTunes. In the future, similar music collections will also be released for Pokémon Diamond/Pearl, Black/White and Black/White 2.
