There's no composer credited for Track 13 on this release ("Sideswing"), but I have "Rinzu Sasou" credited in an mp3. Seeing as Ayako Saso doesn't otherwise have a track on this album, I'm wondering... I mean, it certainly
sounds a lot like her music... but if it is someone else entirely then I guess this can just be taken as "missing composer credits". It doesn't seem too coincidental to me though.
Sorry if this is old hat and you know about it already.
