Growing Wings by Kay Jemsen, the English theme to the Drakengard games, seems fairly readily available. Tsukiru by Eriko Hatsune, the Japanese theme, on the other hand has proven virtually impossible to find.

Anyone got a copy they'd be willing to share? If you have both songs feel free to share them together.

Also, unrelated note, the R-Type Final OST at galbadia hotel is missing the theme to level 3.5, Forest Watchdog. Anyone know where to find it?
