Does anyone have this rip by any chance? since it has the missing tracks

I used to have the complete game rip of TwinSanity you probably speak about, but I don't anymore. However, you can find some extra tracks there : Index of /music/crashtwinsanitymasters (http://kneubuhlmann.com/music/crashtwinsanitymasters/)

You'll find the missing tracks from the official Spiralmouth release such as Dingodile boss fight theme and the N. Gin one. And also FMVs audio withtout the voices.
