I've been trying to find MP3 files and the album artwork for the japanese-only Gatchaman soundtrack albums, but I can't find them anywhere. They aren't even on Kingdom Hearts Insider, which is usually a great resource to find audio files and album artwork for many japanese-only video game and anime soundtracks as well as video game soundtracks that were released over here that are no longer available. And I'm wondering if any MP3's of any of them do exist.
