I use Ecliptic Orbit for information who composed what. And although it is dated now, it bases all composition/arrangement/lyrics/vocal listings based on the OSTs of the IIDX games. and they don't have Aoi Shoudou listed as being sung by Miyuki Kunitake:

Also, considering how many various vocalists NAOKI uses, that girl could be a different girl that has Yuki in her name.
- Fair enough. I'll take it off the page for now until I can get something more solid than the Japanese Wikipedia (since they've been wrong before with jubeat's Invisible World). I still think it's likely though, since Yuki's short for Miyuki and her voice sounds similar to her low voice in songs like Kiss Me All Night Long, Balance, Be Proud, etc. That also reminded me yesterday I own the 8th style OST, so I checked it - and even they don't list any extra vocalist information! The only other tidbit was "TERRA WORKS" coming up with the lyrics. -- Ryujin 14:07, 15 September 2010 (UTC)
