Extract resources (Audio/Music) from PS2 extracted .iso

[Renamon Toast Crunch]

Im trying to rip any and all music and audio files from the game "ROBOT ALCHEMIC DRIVE"

I downloaded the extracted .iso and have a .bin and .cue file. I've use PowerISO to extract both the .bin and .cue files and got the following.

IOPRP250.IMG
CONTROL.DY
OPENING.PSS
REMOTE.DAN
SLUS_204.45
SYSTEM.CNF

Both the .bin and .cue files had the same contents.

I tried to use MFAudiov to extract sound but was only able to find the audio to the video out of the OPENING.PSS file.

(OPENING.PSS plays in VLC as a video with no audio and MFAudio was able to extract the audio from OPENING.PSS)

Any help on this? I literally cant find the music anywhere (At least not the one I want) and tutorials are bad.

EDIT:

I downloaded and tested the program PSound. The file REMOTE.DAN contained 446 SFX sounds but none of the games music. Still searching. The file OPENING.PSS was also opened with PSound and a .m2v and .wav file was discovered, the .m2v was a video and the .wav was the audio to the video.
