Hm, that's interesting to know, I didn't think they were just dumbly interleaved like that. There's got to be a specification of the layout in the header, I'll take a look.

I share AchillesPDX's quest- I too am trying to decode Journey's '.xvag' audio files.
I don't have very much experience in this area, but I have tried VGMstream (latest version as of 11:32-2013/03/28), and ran into what I think is the same issue as AchillesPDX.
I also tried MFAudio with no luck. (on a whim)
I don't wish to bother you all, but if any progress has been made that would make this endeavor achievable, I'd love to know.
Thank you, Facies Secunda

Most of the files in NPUA70218\USRDIR\Data\Sounds\Streams\mus seemed to play for me, but some were still quad channel. Most importantly, the final level is flawless, and that's my favorite one :)
