Zone of the Enders -- ripping the audio

[hanzo_san]

Does anyone know how to rip the music from Zone of the Enders?
There are no .bin, .int, .adx, .vag, .ss2, or .xa2 files anywhere.
Where is the music located? Can someone help me?

I don't really care about ripping the music from the .pss movie files. I just want the music that plays during the stages.

Thanks.
