Does anyone know how to edit the music tracks on a PSX title...

[Branson]

I tried to ask the same question at Megagame forum, unfortunately the guys there were unable to help me on my quest to "put new life in my old PS games".

I know music isn't everything, but if I could just edit the standard audio files on any/all of my PS titles that use normal audio, with, lets say album songs etc. - it'd be great. I'm sure.
