Back in 2009. they released the HeartGold/SoulSilver soundtrack on CD, but there was a bonus: early copies had a special leaflet featuring a QR code. You could then scan the QR code or send a blank email to hscd@pokemon.jp to get two exclusive download-only tracks:
1. Ballad to the Safari Zone (Instrumental Version) (サファリゾーン園歌 (インストバージョン)) 2. Ballad to the Safari Zone (Chorus Version) (サファリゾーン園歌 (合唱バージョン))
A Google search reveals a video featuring the Chorus Version, but the Instrumental Version is nowhere to be found. I tried a couple of Japanese P2P programs, but still no luck. Anyone else have more experience searching for Japanese files?
