In Japan on 28th October 2009, the soundtrack for the newest Pokémon titles, Heart Gold and Soul Silver, was released. The three CD set came with a booklet containing various details and a six page interview with the sound team.
Pokémon fansite Dogasu's Backpack has translated the interview in full along with various members of the Pokémon community. It includes some interesting background on a few tracks in the game (did you know the Safari Zone tune has lyrics?) and discussion on an interesting feature in the new remakes which may please some old-school fans: a GB Player that players obtain after beating both Johto and Kanto Leagues which changes in-game music to the Game Boy versions
"There was never a CD release for the original Gold and Silver, so we thought we could use the GB Player to include the old versions of these tracks and make the fans happy" says Ichinose Gou who was Sound Lead. Kageyama Shouta added "Even though we basically included the GB Player for nostalgia purposes, we also included Game Boy arrangements of the newer stuff...We didn't just transfer the original versions over, either; we re-composed the songs from scratch."
